PNP General Purpose Amplifier
PN3645
This device is designed for use as general purpose amplifiers
and switches requiring collector currents to 500 mA. Sourced
from Process 63. See PN2907A for characteristics.
Absolute Maximum Ratings* TA = 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.
