Applications

• Suppression of inductive switching or other transient events such as EFT and surge voltage at the circuit board level
• ESD protection for components sensitive to IEC 61000-4-2 (Level 4), MIL -STD- 883C, Method 3015.7 , and other industry specifications (See Also the MLE or MLN Series)
• Provides on-board transient voltage protection for ICs and transistors
• Used to help achieve electromagnetic compliance of end products
• Replace larger surface mount TVS Zeners in many applications

Revised: 01/27/20 Metal-Oxide Varistors (MOVs) Surface Mount Multilayer Varistors (MLVs) > AUML Series Explanation of T erms Maximum Continuous DC Working Voltage (VM*(DC)++) This is the maximum continuous DC voltage which may be applied, up to the maximum operating temperature (125ºC), to the ML suppressor. This voltage is used as the reference test point for leakage current and is always less than the breakdown voltage of the device. Load Dump Energy Rating WLD+ This is the actual energy the part is rated to dissipate under Load Dump conditions (not to be confused with the "source energy" of a Load Dump test specification). Maximum Clamping Voltage VC+ This is the peak voltage appearing across the suppressor when measured at conditions of specified pulse current and specified waveform (8/20µs). It is important to note that the peak current and peak voltage may not necessarily be coincidental in time. Leakage Current IL+ In the nonconducting mode, the device is at a very high impedance (approaching 106Ω at its rated working voltage) and appears as an almost open circuit in the system. The leakage current drawn at this level is very low (<25µA at ambient temperature) and, unlike the Zener diode, the multilayer TVS has the added advantage that, when operated up to its maximum temperature, its leakage current will not increase above 500µA. Nominal Voltage VNDC++ This is the voltage at which the AUML enters its conduction state and begins to suppress transients. In the automotive environment this voltage is defined at the 10mA point and has a minimum (VN(DC) MIN) and maximum (VN(DC) MAX) voltage specified. Additional Information Datasheet SamplesResources
