KSC1173YTU NPN Power Transistor
IC 3 Amps
Hfe 110 @ .5A
Very good gain, and excellent linearity, same as the 2SC1173 transistor, excellent price versus performance ratio.
Low base to emitter resistance, good for use as a grounded base amplifier.
Useful as a linear power amplifier from Audio to 30 MHz, higher if used in a common base amplifier. Note that 10M you will need decent drive to make the transistor deliver full power.
Price of $2.55 at RF Parts, we are a lot cheaper.
Sorry, but this is the last available lot, these devices are no longer available from my distributors.
