| PN4275 Discrete POWER & Signal Technologies PN4275 C BE TO-92 NPN Switching Transistor This device is designed for high speed saturated switching applications at currents to 100 mA. Sourced from Process 21. See PN2369A for characteristics. Absolute Maximum Ratings* Symbol VCEO VCBO VEBO IC TJ, Tstg Collector-Emitter Voltage Collector-Base Voltage Emitter-Base Voltage Collector Current - Continuous TA = 25C unless otherwise noted Parameter Value 15 40 4.5 200 -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.
