PNP General Purpose Amplifier
This device is digned for general purpose amplifier applications
at collector currents to 300 mA. Sourced from Procs 68.
Absolute Maximum Ratings* TA = 25°C unls otherwise ted
*The ratings are limiting valu above which the serviceability of any semiconductor device may be impaired.
T:
1) The ratings are based on a maximum junction temperature of 150 degre C.
2) The are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
