APPLICATION NOTES  
Response Time  
minimum lead lengths 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  
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 6.  
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 7. 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 < 1.0 ns and negligible  
inductance. However, external inductive effects could  
produce unacceptable overshoot. Proper circuit layout,  
Some input impedance represented by Z is essential to  
in  
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 8. Average power must be derated as the lead or  
ambient temperature rises above 25C. 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 8 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 8 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  
including Strike Voltage Breakdown test, Endurance  
Conditioning, Temperature test, Dielectric  
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  
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.
