Symbol Parameter Value Units
VCES Collector-Emitter Voltage 300 V VCBO Collector-Base Voltage 300 V VEBO Emitter-Base Voltage 6.0 V IC Collector Current - Continuous 500 mA TJ, Tstg Operating and Storage Junction Temperature Range -55 to +150 °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 operations.
