Sourced from Process 10. See PN100A for characteristics. Absolute Maximum Ratings* TA = 25C unless otherwise noted Symbol Parameter Value Units V Collector-Emitter Voltage 45 V CEO V Collector-Base Voltage 50 V CES V Emitter-Base Voltage 6.0 V EBO I Collector Current - Continuous 500 mA C Operating and Storage Junction Temperature Range -55 to +150 C T , T J stg *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.
