APPLICATION NOTES
Response Time
In most applications, the transient suppressor device is
placed in parallel with the equipment or component to be
protected. In t his situation, t here i s a t ime d elay associated w ith
the capacitance of the device and an overshoot condition
associated w ith t he inductance o f t he d evice a nd t he i nductance
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 r equired f or t he d evice t o g o f rom z ero c urrent t o f ull
current) and lead i nductance. T his i nductive e f fect p roduces a n
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 Zin 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 p ower m ust b e d erated a s the l ead o r a mbient
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 ms 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.

UL RECOGNITION
The entire series has Underwriters Laboratory
Recognition for the classification of protectors (QVGQ2)
under the UL standard for safety 497B and File #E210057.
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.
