BC846A / BC846B / BC847A / BC847B / BC847C
NPN General Purpose Amplifier
This device is designed for low noise, high gain, general purpose
amplifier applications at collector currents from 1.0 µA to 50 mA.
Sourced from Process 07.
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.
