Description

The SARS10 is an 800 V silicon diode designed especially for use in high-efficiency snubber circuits. This diode can sustain a high voltage with low loss, with low-noise rectification. To suppress surge voltage with low noise, conduct the surge voltage and noise into a capacitor. A series resistor, R S , of 22 Ω is built into the SARS10, eliminating a external component. Then allow the capacitor to discharge the energy into power supply line with the regenerative circuit operation, shown below in the typical application circuit schematic.

SANKEN ELECTRIC CO., LTD. SARS10-DS SARS10 September 28, 2011 High Efficiency Snubber Diode Because reliability can be affected adversely by improper storage environments and handling methods, please observe the following cautions. Cautions for Storage

  • Ensure that storage conditions comply with the standard temperature (5°C to 35°C) and the standard relative humidity (around 40% to 75%); avoid storage locations that experience extreme changes in temperature or humidity.
  • Avoid locations where dust or harmful gases are present and avoid direct sunlight.
  • Reinspect for rust on leads and solderability of the products that have been stored for a long time. Cautions for Testing and Handling When tests are carried out during inspection testing and other standard test periods, protect the products from power surges from the testing device, shorts between the product pins, and wrong connections. Ensure all test parameters are within the ratings specified by Sanken for the products. Remarks About Using Silicone Grease with a Heatsink
  • When silicone grease is used in mounting the products on a heatsink, it shall be applied evenly and thinly. If more silicone grease than required is applied, it may produce excess stress.
  • V olatile-type silicone greases may crack after long periods of time, resulting in reduced heat radiation effect. Silicone greases with low consistency (hard grease) may cause cracks in the mold resin when screwing the products to a heatsink. Our recommended silicone greases for heat radiation purposes, which will not cause any adverse effect on the product life, are indicated below: Type Suppliers G746 Shin-Etsu Chemical Co., Ltd. YG6260 Momentive Performance Materials Inc. SC102 Dow Corning Toray Co., Ltd. Cautions for Mounting to a Heatsink
  • When the flatness around the screw hole is insufficient, such as when mounting the products to a heatsink that has an extruded (burred) screw hole, the products can be damaged, even with a lower than recommended screw torque. For mounting the products, the mounting surface flatness should be 0.05 mm or less.
  • Please select suitable screws for the product shape. Do not use a flat-head machine screw because of the stress to the products. Self-tapping screws are not recommended. When using self-tapping screws, the screw may enter the hole diagonally, not vertically, depending on the conditions of hole before threading or the work situation. That may stress the products and may cause failures.
  • Recommended screw torque: 0.490 to 0.686 N ●m (5 to 7 kgf ● cm).
  • For tightening screws, if a tightening tool (such as a driver) hits the products, the package may crack, and internal stress fractures may occur, which shorten the lifetime of the electrical elements and can cause catastrophic failure. Tightening with an air driver makes a substantial impact. In addition, a screw torque higher than the set torque can be applied and the package may be damaged. Therefore, an electric driver is recommended. When the package is tightened at two or more places, first pre-tighten with a lower torque at all places, then tighten with the specified torque. When using a power driver, torque control is mandatory. Soldering
  • When soldering the products, please be sure to minimize the working time, within the following limits: 260±5°C 10±1 s (Flow, 2 times) 380±10°C 3.5±0.5 s (Soldering iron, 1 time)
  • Soldering should be at a distance of at least 2.0 mm from the body of the products. Electrostatic Discharge
  • When handling the products, the operator must be grounded. Grounded wrist straps worn should have at least 1 MΩ of resistance from the operator to ground to prevent shock hazard, and it should be placed near the operator.
  • Workbenches where the products are handled should be grounded and be provided with conductive table and floor mats.
  • When using measuring equipment such as a curve tracer, the equipment should be grounded.
  • When soldering the products, the head of soldering irons or the solder bath must be grounded in order to prevent leak voltages generated by them from being applied to the products.
  • The products should always be stored and transported in Sanken shipping containers or conductive containers, or be wrapped in aluminum foil.

  • Application and operation examples described in this document are quoted for the sole purpose of reference for the use of the prod- ucts herein and Sanken can assume no responsibility for any infringement of industrial property rights, intellectual property rights or any other rights of Sanken or any third party which may result from its use.
  • Although Sanken undertakes to enhance the quality and reliability of its products, the occurrence of failure and defect of semicon- ductor products at a certain rate is inevitable. Users of Sanken products are requested to take, at their own risk, preventative measures including safety design of the equipment or systems against any possible injury, death, fires or damages to the society due to device failure or malfunction.
  • Sanken products listed in this document are designed and intended for the use as components in general purpose electronic equip- ment or apparatus (home appliances, office equipment, telecommunication equipment, measuring equipment, etc.). When considering the use of Sanken products in the applications where higher reliability is required (transportation equipment and its control systems, traffic signal control systems or equipment, fire/crime alarm systems, various safety devices, etc.), and whenever long life expectancy is required even in general purpose electronic equipment or apparatus, please contact your nearest Sanken sales representative to discuss, prior to the use of the products herein. The use of Sanken products without the written consent of Sanken in the applications where extremely high reliability is requi red (aerospace equipment, nuclear power control systems, life support systems, etc.) is strictly prohibited.
  • In the case that you use Sanken products or design your products by using Sanken products, the reliability largely depends on the degree of derating to be made to the rated values. Derating may be interpreted as a case that an operation range is set by derating the load from each rated value or surge voltage or noise is considered for derating in order to assure or improve the reliability. In general, derating factors include electric stresses such as electric voltage, electric current, electric power etc., environmental stresses such as ambient temperature, humidity etc. and thermal stress caused due to self-heating of semiconductor products. For these stresses, instantaneous values, maximum values and minimum values must be taken into consideration. In addition, it should be noted that since power devices or IC's including power devices have large self-heating value, the de gree of derating of junction temperature affects the reliability significantly.
  • When using the products specified herein by either (i) combining other products or materials therewith or (ii) physically, chemically or otherwise processing or treating the products, please duly consider all possible risks that may result from all such uses in advance and proceed therewith at your own responsibility.
  • Anti radioactive ray design is not considered for the products listed herein.
  • Sanken assumes no responsibility for any troubles, such as dropping products caused during transportation out of Sanken's distribu- tion network.
