Hi, I&x27;m trying to diagnose the circuit for the old tape echo machine but I have some problems with finding out where does the supply voltage come for example to the transistor T6, T7 and T8 on the following drawing (pink lines). T2, T3 and T4 look pretty straightforward as getting the voltage supply.
Kinds of Transistors - BJT, FET, JFET, MOSFET, IGBT & Particular Transistors. Conceptos Bsicos. Completely different Kinds of Subject Impact, Bipolar Junction, Depletion, Enhancement, Insulated Gate Bipolar and Particular Transistors . BJT. BJT or Bipolar Junction Transistor is a kind of transistor that&x27;s bipolar and has a junction.
seaching for P channel mosfets proves to be difficult. Cant use IGBT, same problem as the N channel mosfet, unless there is a P channel version Using NPNPNP means power loss of 5w or more. Furthermore, its hard to find a high voltage, high amp PNPNPN with high gain 100. The failure modes for the IGBT are in the form of degradation of certain key electrical parameters (e.g., leakage current, threshold voltage) or the loss of functionality (inability to turn-off). The failure causes can be due to environmental conditions or operating conditions. For example, failures > could be caused by high.

The IGBT combines features of the BJT and MOSFET. It has the simpler, voltage con-trolled gate drive of the MOSFET and the high current capability of the BJT. This combination has made the IGBT the preferred de-vice for high power applications. They share advantages & disadvantages of both devices Voltage Control - Like the MOSFET, a voltage.
