 · Germanium transistors were pretty much obsoleted forty years ago, by silicon transistors. There is a far better range of silicon transistors, and generally they have far better specs than germanium transistors. The only reason you'd use a germanium transistor at this time is if there was a specific reason for using germanium. There are still some

It would just if it drops to less than 10 with a high current load. Ge PNP power transistors were used a lot in low voltage switching power supplies. The Low Vce drop allowed a power supply I found from the 1960's to output 16VDC from a salt water battery! 2N2728 in pushpull. The Vcesat was ~70mV 50Amps!

Germanium transistor projects intrigued experimenters from the early days in the 1950s until the early 1970s. In the Seventies, the highergrade silicon devices began to take over the hobby market. Hobbyists adapted, by attempting germaniumtosilicon conversions. Often, the germanium circuits didn't cooperate. Several difficulties occurred.

 · PNP Transistor Example. Consider a PNP transistor, which is connected in the circuit with the supply voltages VB =, VE = 2V, +VCC = 10V and –VCC = 10V. And also this circuit connected with the resistors of RB = 200kΩ and RE = RC (or RL) = 5kΩ. Now calculate the current gain values (α, β) of the PNP transistor.
