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 capacitance

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 7.

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 8. 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 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 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 b e

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 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 (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

flammability test for the package material, we have been

recognized for much more to be included in their Protector

category.

CLIPPER BIDIRECTIONAL DEVICES

1. Clipper-bidirectional devices are available in the

1.5KEXXA series and are designated with a “CA”

suffix; for example, 1.5KE18CA. Contact your nearest

ON Semiconductor representative.

2. Clipper-bidirectional part numbers are tested in both

directions to electrical parameters in preceeding table

(except for VF which does not apply).

3. The 1N6267A through 1N6303A series are JEDEC

registered devices and the registration does not include

a “CA” suffix. To order clipper-bidirectional devices

one must add CA to the 1.5KE device title.
