PN3644

PN3644 Discrete POWER & Signal Technologies PN3644 C BE TO-92 PNP General Purpose Amplifier This device is designed for use as general purpose amplifiers and switches requiring collector currents to 500 mA. Sourced from Process 63. See PN2907A for characteristics. Absolute Maximum Ratings* Symbol VCEO VCBO VEBO IC TJ, Tstg Collector-Base Voltage Emitter-Base Voltage Collector Current - Continuous TA = 25°C unless otherwise noted Parameter Collector-Emitter Voltage Value 45 45 5.0 800 -55 to +150 Units V V V mA °C Operating and Storage Junction Temperature Range *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.
