GENERAL DATA 1500 WATT PEAK POWER APPLICATION NOTES RESPONSE TIME In most applications, the transient suppressor device ts placed in parallel with the equipment or component to be pro- tected. In this situation, there ts a time delay associated with the capacitance of the device and an overshoot condition associated with the inductance of the device and the induc- tance of the connection method. The capacitive effect is of mi- nor importance in the parallel protection scheme because It only produces a time delay in the transition from the operating voltage to the clamp voltage as shown in Figure 5. The inductive effects in the device are due to actual turn-on time (time required for the device to go from zero current to full current) and lead inductance. This inductive effect produces an overshoot in the voltage across the equipment or compo- nent being protected as shown in Figure 6. Minimizing this overshoot is very important in the application, since the main purpose for adding a transient suppressor is to clamp voltage spikes. The SMC series have a very good response time, typi- cally < 1 ns and negligible inductance. However, externa! inductive effects could produce unacceptable overshoot. Proper circuit layout, minimum lead lengths and placing the suppressor device as close as possible to the equipment or components to be protected will minimize this overshoot. Some input impedance represented by Z;n is essential to prevent overstress of the protection device. This impedance should be as high as possible, without restricting the circuit operation. DUTY CYCLE DERATING The data of Figure 1 applies for non-repetitive conditions and at a lead temperature of 25C. If the duty cycle increases, the peak power must be reduced as indicated by the curves of Figure 7. Average power must be derated as the lead or ambi- ent temperature rises above 25C The average power derat- ing curve normally given on data sheets may be normalized and used for this purpose. At first glance the derating curves of Figure 7 appear to be in error as the 10 ms pulse has a higher derating factor than the 10 ys pulse. However, when the derating factor for a given puise of Figure 7 1s multiplied by the peak power value of Fig- ure 1 for the same pulse, the results follow the expected trend.
