BC368
NPN General Purpose Amplifier
This device is designed for general purpose medium power
amplifiers and switches requiring collector currents to 1.5 A.
Sourced from Process 37.
Absolute Maximum Ratings* T A = 25°C unless otherwise noted
*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
