T the cracken New Member Feb 27, 2010 #1 here is a transistor i have and i cant make heads or tails of this spec help plz thanks SFT323 Ge PNP Lo-Pwr BJT Various V(BR)CBO (V)=24 I(C) Abs.(A) Collector Current=250m Absolute Max. Power Diss. (W)=200m I(CBO) Max. (A)=15u h(FE) Min. Static Current Gain=85 @I(C) (A) (Test Condition)=100m @V(CE) (V) (Test Condition)=1.0 f(T) Min. (Hz) Transition Freq=2.6M Status=Discontinued Package=TO-1 Military=N SFT323 Germanium PNP N/A Category: Germanium Transistor, PNP Transistor, Transistor MHz: <1 MHz Amps: 0.5A Volts: 32V

Hero999 Banned Feb 27, 2010 #2 It's a Germanium transistor which means it's very old, obsolete and is no longer be made: status = discontinued. What spec's are you having problems with? It looks fairly standard to me.

What spec's are you having problems with? It looks fairly standard to me. Click to expand... i want to make a simple amp from one. so i guess what ever i need to do that

Hero999 Banned Feb 27, 2010 #4 You mean a common emitter amplifier? You really haven't provided enough information but you could help yourself first by using a transistor which is still made.

Click to expand... yes a common emitter amp will do. thats all the information that i could find. What information am i missing?
