Description

These devices are designed to protect voltage sensitive

components from high voltage, high−energy transients.

They have excellent clamping capability, high surge

capability, low zener impedance an d fast response time.

These devices are Littelfuse’s exclusive, cost-effective,

highly reliable, axial leaded package and are ideally-suited

for use in communication systems, numerical controls,

process controls, medical equipment, business machines,

power supplies and many other industrial/consumer

applications, to protect CMOS, MOS and Bipolar

integrated circuits.

Additional Information

Maximum ratings are those values beyond which device damage can occur. Maximum

ratings applied to the device are individual stress limit values (not normal operating

conditions) and are not valid simultaneously. If these limits are exceeded, device

functional operation is not implied, damage may occur and reliability may be affected.

Application Notes

ResponseTime

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.

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 8.

Duty Cycle Derating

The data of Figure 1 applies for non-repetitive

conditions and at a lead temperature of 25ºC. 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 25ºC. The average

power derating curve normally given on data sheets

may be normalized and used for this purpose.

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 9. 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,

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.

Typical Protection Circuit

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 Bi-Directional 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 Littelfuse representative.

2. Clipper-bidirectional part numbers are tested

in both directions to electrical parameters in

preceding 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.
