NTE385
Silicon NPN Transistor
Audio Power Amp, Switch
Description:
The NTE385 is a silicon NPN transistor in a TO3 type package designed for high voltage, high speed,
power switching in inductive circuits where fall time is critical. It is particularly suited for line operated
switch mode applications.
