APPLICATION NOTES
Response Time
In most applications, the transient suppressor device is
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 capacitive 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 4.
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 5. Minimizing this
overshoot is very important in the application, since the main
purpose for adding a transient suppressor is to clamp voltage
spikes. The SMB series have a very good response time,
typically < 1 ns and negligible inductance. However, external
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 in 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 25 ? C. If the duty cycle increases,
the peak power must be reduced as indicated by the curves of
Figure 6. 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 6 appear to be
in error as the 10 ms pulse has a higher derating factor than
the 10 m s pulse. However, when the derating factor for a
given pulse of Figure 6 is multiplied by the peak power value
of Figure 1 for the same pulse, the results follow the
expected trend.
