C C E E
C B TO-92 SOT-23 E C
B B SOT-223 Mark: 1D NPN High Voltage Amplifier
This device is designed for application as a video output to
drive color CRT and other high voltage applications. Sourced
from Process 48. Absolute Maximum Ratings*
Symbol TA = 25°C unless otherwise noted 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. Thermal Characteristics
