NPN General Purpose Amplifier

This device is designed for use as general purpose amplifiers and switches requiring collector currents to 300 mA. Sourced from

Process 10. See PN100A for characteristics.

Absolute Maximum Ratings*		TA = 25°C unless otherwise noted
Symbol	Parameter		Value	Units
VCEO	Collector-Emitter Voltage		45	V
VCES	Collector-Base Voltage		50	V
VEBO	Emitter-Base Voltage		6.0	V
IC	Collector Current - Continuous		500	mA
TJ, Tstg	Operating and Storage Junction Temperature Range		-55 to +150	°C

*These ratings are limiting values above which the serviceability of any semiconductor device may be impaired.

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.
