2N2646 – 2N2647

SILICON UNIJUNCTION TRANSISTORS

Silicon Planar Unijunction Transistors have a structure resulting in lower saturation voltage, peak-point

current and valley current as zell as a much higher base-one peak pulse voltage. In addition, these

devices are much faster switches.

The 2N2646 is intended for general purpose industrial applications where circuit economy is of primary

importance, and is ideal for use in firing circuits for Silicon Controlled Rectifiers and other applications

where a guaranteed minimum pulse amplitude is required. The 2N2647 is intended for applications where

a low emitter leakage current and a low peak point emitter current (trigger current) are required and also

for triggering high power SCR’s.
