NPN General Purpose Amplifier

PN3643

This device is designed for use as general purpose amplifiers

and switches requiring collector currents to 300 mA. Sourced

from Process 10. See PN100 for characteristics.

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.
