ABSOLUTE MAXIMUM RATINGS

Input Voltage

Q12 models

Volts, max. continuous

0-36 VDC to rated specifications

Volts, transient, 100 mSec

50 VDC, no damage

Q48 models

Volts, max. continuous

0-75 VDC to rated specifications

Volts, transient, 100 mSec

100 VDC, no damage

On/Off control, referred to –Vin

-0.7 V. min to +15V max.

Input Reverse Polarity Protection

None, install external fuse

Output Overvoltage

Output Current

Current-limited. Devices can

withstand sustained short circuit

without damage. The outputs are

not intended to accept appreci-

able reverse current.

Overtemperature Protection

Device includes electronic over-

temperature shutdown protection

under normal operation.

Storage Temperature

-55 to +125

° C.

Lead Temperature

See soldering specifications

Absolute Maximum Ratings

Absolute maximums are stress ratings. Exposure of devices to

greater than any of these conditions may adversely affect long-term

reliability. Proper operation under conditions other than those listed

in the Performance/Functional Specifications Table is not implied nor

recommended.

Maximum Ratings Notes

The transient specifications indicate that sample lots were success-

fully tested for 100 mS at the transient stress voltage and were not

damaged. As a practical matter in your application, it is often difficult

to determine how long an input overvoltage was applied. Therefore,

do not exceed the continuous voltage rating.
