DEVICE
DESCRIPTION
The 2N1893 is a Silicon Planar Epitaxial NPN
transistor in Jedec TO-39 metal case, designed
for use in high-performance amplifier, oscillator
and switching circuits. It provides greater voltage
swings in oscillator and amplifier circuits and
more protection in inductive switching circuits due
to its 120 V collector-to-base voltage rating.
