Sourced from Process 68. 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 45 50 5.0 500 -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.
