The P6KE6.8A series is designed to protect voltage sensitive
components from high voltage, high energy transients. They have
excellent clamping capability, high surge capability, low zener
impedance and fast response time. These devices are
ON Semiconductor’s exclusive, cost-effective, highly reliable
Surmetic axial leaded package and is ideally-suited for use in
communication systems, numerical controls, process controls,
medical equipment, business machines, power supplies and many
other industrial/consumer applications.

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.
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 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. The P6KE6.8A series
has very good response time, typically < 1 ns and negligible
inductance. However, external inductive effects could
produce unacceptable overshoot. Proper circuit layout,
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 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 6 is multiplied by the peak power value
of Figure 1 for the same pulse, the results follow the
expected trend.

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.
The entire series including the bidirectional CA suffix has
Underwriters Laboratory Recognition for the classification
of protectors (QVGV2) under the UL standard for safety
497B and File #E 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
