NPN General Pupose Amplifier
This device is designed for use as a medium power amplifier and switch requiring collector currents up to 500 mA.
Absolute Maximum Ratings* TA = 25°C unless otherwise noted
| Symbol | Parameter | Value | Units |
| VCEO | Collector-Emitter Voltage | 40 | V |
| VCBO | Collector-Base Voltage | 60 | V |
| VEBO | Emitter-Base Voltage | 6.0 | V |
| IC | Collector Current - Continuous | 600 | 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.
