2N4402 C TO-92 B E PNP General Purpose Amplifier This device is designed for use as general purpose amplifiers and switches requiring collector currents to 500 mA. Absolute Maximum Ratings* TA = 25°C unless otherwise noted Symbol Parameter Value Units VCEO Collector-Emitter Voltage 40 V V Collector-Base Voltage 40 V CBO VEBO Emitter-Base Voltage5.0V ICCollector Current - Continuous600mA -55 to +150 TJ, Tstg Operating and Storage Junction Temperature Range °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 ope
