Silicon NPN Transistor
HV Darlington Power Amp, Switch
Description:
The NTE97 is a silicon NPN Darlington transistor in a TO3 type package designed for high voltage,
high–speed, power switching in inductive circuits where fall–time is critical. They are particularly
suited for line operated switch–mode applications.

Note 3. The internal Collector–Emitter diode can eliminate the need for an external diode to clamp
inductive loads. Tests have shown that the Forward Recovery Voltage (V
) of this diode is
F
comparable to that of typical fast recovery rectifiers.
