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

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.

UL RECOGNITION*

The entire series has Underwriters Laboratory Recognition

for the classification of protectors (QVGV2) under the UL

standard for safety 497B and File #116110. 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 flammabil-

ity test for the package material, we have been recognized for

much more to be included in their Protector category.
