Mosorb 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 and fast response time. These devices are Motorola’s exclusive,
cost-effective, highly reliable Surmetic 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.

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 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 unacceptable overshoot. Proper circuit layout, minimum lead lengths
500 Watt Peak Power Data Sheet
4-4
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 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 flammability test for the package material, we have been recognized for
much more to be included in their Protector category.
