TO-92

SOT-23 Mark: ZF

PNP General Purpose Amplifier This device is designed for general purpose amplifier and switch- ing applications at collector currents to 10 µA as a switch and to 100 m A as an amplifier.

Absolute Maximum Ratings* TA = 25°C unless otherwise noted Symbol Parameter Value Units VCEO Collector-Emitter Voltage VCBO Collector-Base Voltage VEBO Emitter-Base Voltage 4.0 IC Collector Current - Continuous m A

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. 3) All voltages (V) and currents (A) are negative polarity for PNP transistors.
