D, DUTY CYCLE (%)  
Figure 7. Typical Derating Factor for Duty Cycle  
APPLICATION NOTES  
RESPONSE TIME  
and placing the suppressor device as close as possible to the  
equipment or components to be protected will minimize this  
overshoot.  
In most applications, the transient suppressor device is  
placed in parallel with the equipment or component to be pro-  
tected. In this situation, there is a time delay associated with  
the capacitance of the device and an overshoot condition as-  
sociated 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 volt-  
age to the clamp voltage as shown in Figure A.  
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  
component being protected as shown in Figure B. 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 unaccept-  
able overshoot. Proper circuit layout, minimum lead lengths  
Some input impedance represented by Z is essential to  
in  
prevent overstress of the protection device. This impedance  
shouldbeashighaspossible, withoutrestrictingthecircuitop-  
eration.  
DUTY CYCLE DERATING  
The data of Figure 1 applies for non-repetitive conditions  
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 7. 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.  
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 µs pulse. However, when the derating factor for a given  
pulse of Figure 7 is multiplied by the peak power value of  
Figure 1 for the same pulse, the results follow the expected  
trend.
