GENERAL PURPOSE HIGH-VOLTAGETYPE
DESCRIPTIO N
The 2N1893 is a silicon planar epitaxial NPN transistorinJedec TO-39metal case,designed for use
inhigh-performance amplifier,oscillator andswitching circuits.
It provides greater voltage swings in oscillator and
amplifier circuits and more protection in inductive
switchingcircuits due toits 120 V collector-to-base
voltage rating.
Productsapproved to CECC50002-104 available onrequest.
