PNP General Purpose Amplifier

2N4125

This device is designed for use as general purpose amplifiers

and switches requiring collector currents of 10

µA to 100 mA.

Absolute Maximum Ratings*

TA = 25°C unless otherwise noted

NOTES:

1) These ratings are based on a maximum junction temperature of 150 degrees C.

2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
