RESPONSE TIME
placed in parallel with the equipment or component to be
protected. In this situation, there is a time delay associated with
the capacitance of the device and an overshoot condition
associated with the inductance of the device and the inductance
of the connection method. The capacitance effect is of minor
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 6.
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 component
being protected as shown in Figure 7. Minimizing this
overshoot is very important in the application, since the main
purpose for adding a transient suppressor is to clamp voltage
spikes. These devices have excellent response time, typically
in the picosecond range and negligible inductance. However,
external inductive effects could produce unacceptable
overshoot. Proper circuit layout, minimum lead lengths and

and at a lead temperature of 25°C. If the duty cycle increases,
the peak power must be reduced as indicated by the curves of
Figure 5. Average power must be derated as the lead or ambient
temperature rises above 25°C. The average power derating
curve normally given on data sheets may be normalized and
used for this purpose.

10 ms pulse. However, when the derating factor for a given
pulse of Figure 5 is multiplied by the peak power value of
Figure 1 for the same pulse, the results follow the expected
trend.
