Bipolar junction transistor - Wikipedia

A bipolar junction transistor (bipolar transistor or BJT) is a type of transistor that uses both electrons and holes as charge carriers.. Unipolar transistors, such as field-effect transistors, only use one kind of charge carrier.BJTs use two junctions between two semiconductor types, n-type and p-type.. BJTs are manufactured in two types: NPN and PNP, and are available as individual ...

PNP Transistor Tutorial - The Bipolar PNP Transistor

To cause the Base current to flow in a PNP transistor the Base needs to be more negative than the Emitter (current must leave the base) by approx 0.7 volts for a silicon device or 0.3 volts for a germanium device with the formulas used to calculate the Base resistor, Base current or Collector current are the same as those used for an equivalent ...

Alloy-junction transistor - Wikipedia

The germanium alloy-junction transistor, or alloy transistor, was an early type of bipolar junction transistor, developed at General Electric and RCA in 1951 as an improvement over the earlier grown-junction transistor.. The usual construction of an alloy-junction transistor is a germanium crystal forming the base, with emitter and collector alloy beads fused on opposite sides.
