TVS Diodes 1500 Watt Zener Transient Voltage Suppressors Application Notes Response Time minimum lead lengths and placing the suppressor device as close as possible to the equipment or In most applications, the transient suppressor device components to be protected will minimize this is placed in parallel with the equipment or component overshoot. Some input impedance represented by Zin to be protected. In this situation, there is a time is essential to prevent overstress of the protection delay associated with the capacitance of the device device. This impedance should be as high as possible, and an overshoot condition associated with the without restricting the circuit operation. inductance of the device and the inductance of the connection method. The capacitance effect is of minor Duty Cycle Derating importance in the parallel protection scheme because it only produces a time delay in the transition from the The data of Figure 1 applies for non-repetitive operating voltage to the clamp voltage as shown in conditions and at a lead temperature of 25ºC. If Figure 8. the duty cycle increases, the peak power must be reduced as indicated by the curves of Figure The inductive effects in the device are due to actual 7. Average power must be derated as the lead or turn-on time (time required for the device to go from ambient temperature rises above 25ºC. The average zero current to full current) and lead inductance. This power derating curve normally given on data sheets inductive effect produces an overshoot in the voltage may be normalized and used for this purpose. across the equipment or component being protected as shown in Figure 9. Minimizing this overshoot is At first glance the derating curves of Figure 7 very important in the application, since the main appear to be in error as the 10 ms pulse has a higher purpose for adding a transient suppressor is to clamp derating factor than the 10 µs pulse. However, when voltage spikes. These devices have excellent response the derating factor for a given pulse of Figure 7 is time, typically in the picosecond range and negligible multiplied by the peak power value of Figure 1 for the inductance. However, external inductive effects could same pulse, the results follow the expected trend. produce unacceptable overshoot. Proper circuit layout, © 2017 Littelfuse, Inc.

TVS Diodes 1500 Watt Zener Transient Voltage Suppressors Typical Protection Circuit UL Recognition* The entire series has Underwriters Laboratory Recognition for the classification of protectors (QVGV2) under the UL standard for safety 497B and File #116110. Many competitors only have one or two devices recognized or have recognition in a non-protective category. Some competitors have no recognition at all. With the UL497B recognition, our parts successfully passed several tests including Strike Voltage Breakdown test, Endurance Conditioning, Temperature test, Dielectric Voltage- Withstand test, Discharge test and several more. Whereas, some competitors have only passed a flammability test for the package material, we have been recognized for much more to be included in their Protector category. *Applies to 1.5KE6.8A, CA thru 1.5KE250A, CA Clipper Bi-Directional Devices 1. Clipper-bidirectional devices are available in the 1.5KEXXA series and are designated with a “CA” suffix; for example, 1.5KE18CA. Contact your nearest Littelfuse representative. 2.
