n Six model sizes equivalent to standard disc varistors n Smaller nominal dimensions than disc varistors n Broad range of current and energy handling capabilities n +85 °C Continuous operating temperature n Low clamping voltage n Available with straight or crimped leads n Available in tape and reel packaging for automatic pick-and-place n RoHS compliant* General Information The SV series is a series of lead style epoxy coated square or rectangular shaped varistors with an AC operating voltage ranging from 60 V to 550 V. This series offers both standard and custom options. The standard offering consists of square shaped varistors with extremely high current and energy capabilities and a low clamping voltage, providing an increased level of protection for the transients expected in telecommunication and AC power networks. Compared to electrically equivalent disc varistors, SV varistors are produced with smaller nominal dimensions. In addition to the standard offering, customers are offered the option to design their own customized varistor to suit their specific application needs. Parameters free to be chosen are: non-standard DC/AC operating voltage, leakage current, clamping voltage, maximum surge current, energy absorption level, maximum dissipation power as well as shape - the dimensions being the function of required electrical parameters and vice-versa. Summary of Custom Varistor Options n DC operating voltage range (Vdc): 85 V to 745 V (up to 1300 V for customized products) n AC operating voltage range (Vrms): 60 V to 550 V (up to 1000 V for customized products) n Six standard sizes available; other cutomized sizes available upon request n Broad range of current and energy handling capabilities n +85 °C Continuous operating temperature n Available electrical parameter options: AC/DC operating voltage, leakage current, clamping voltage, maximum surge current, energy absorption level, maximum dissipation power and threshold voltage temperature coefficient n Available in tape and reel packaging for automatic pick-and-place n Model SVxxxK20 with Imax = 1 x 15 kA @ 8/20 µs is available upon request n Model SVxxxK23 with Imax = 1x 20 kA @ 8/20 µs is available upon request SV550 K 20 Varistor Symbol U ** Not all rated voltages are UL recognized; check the file for details.

Assembly Recommendations for Through-Hole Components POINT TO BE FIXED (.079) Very often before soldering through-hole components, their leads get bent. It is important not to damage the components during lead bending. Damage most commonly incurred during bending is cracks in epoxy parts, which can lead to increased humidity sensitivity of a component and, consequentially, a shorter lifetime. In order to avoid epoxy damage, it is necessary to: - fix the most sensitive point (epoxy parts) of a component body - bend the wire at least 2 mm below the end of epoxy parts Other potential damage to a component which can lead to component failure or a shorter lifetime is thermal shock during manual soldering with a soldering iron. This can occur when a soldering iron is placed too close to one point of the component body and it happens most often when the solder joint is too close to the varistor body. Resistance to Soldering Heat In the case of automatic wave soldering, it is important to provide sufficient resistance to soldering heat. In order to prevent any potential problems, internal standards were introduced for testing the resistance to soldering heat of through-hole components: 300 °C, 10 seconds. Pb-free Wave Soldering Profile Recommendations Recommended soldering profiles for all above components are in accordance with JEDEC standard curves (J-STD-020D) and are, therefore, compatible with the Pb-free process.

This legal disclaimer applies to purchasers and users of Bourns® products manufactured by or on behalf of Bourns, Inc. and its affiliates (collectively, “Bourns”). Unless otherwise expressly indicated in writing, Bourns® products and data sheets relating thereto are subject to change without notice. Users should check for and obtain the latest relevant information and verify that such information is current and complete before placing orders for Bourns® products. The characteristics and parameters of a Bourns® product set forth in its data sheet are based on laboratory conditions, and statements regarding the suitability of products for certain types of applications are based on Bourns’ knowledge of typical requirements in generic applications. The characteristics and parameters of a Bourns® product in a user application may vary from the data sheet characteristics and parameters due to (i) the combination of the Bourns® product with other components in the user’s application, or (ii) the environment of the user application itself. The characteristics and parameters of a Bourns® product also can and do vary in different applications and actual performance may vary over time. Users should always verify the actual performance of the Bourns® product in their specific devices and applications, and make their own independent judgments regarding the amount of additional test margin to design into their device or application to compensate for differences between laboratory and real world conditions. Unless Bourns has explicitly designated an individual Bourns® product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949) or a particular qualification (e.g., UL listed or recognized), Bourns is not responsible for any failure of an individual Bourns® product to meet the requirements of such industry standard or particular qualification.
