Question

The emitter of the transistor should be?


Open in App
Solution

Transistor emitter:

  1. The transistor's emitter is heavily doped, and its job is to emit and inject electrons (or holes for PNP) into the base.
  2. An emitter is one of the transistor's terminals.
  3. The emitter terminal is the most heavily doped field in comparison to the base and collector.
  4. This is because the emitter's job is to supply charge carriers to the collector via the foundation.
  5. The emitter is larger than the collector but smaller than the base.
  6. To overcome heat dissipation, the collector has the most surface area.

Thus, the emitter of the transistor should be heavily doped.
