Transistor: answer key, US style, sheet 2 of 2

  1. Fig. 1

    BCE

    Name NPN transistor

    A bipolar transistor has base, collector and emitter terminals. In the current-controlled model used here, base drive controls conduction between collector and emitter.

  2. Fig. 2

    BCE

    Name PNP transistor

    The arrow is always on the emitter. It points out of the transistor for NPN and into it for PNP, whichever way the symbol is rotated.

  3. Fig. 3

    GDS

    Name N-channel MOSFET

    A MOSFET uses gate voltage relative to source to control its channel between drain and source. The three-terminal form shown here connects its body internally to source.

  4. Fig. 4

    GDS

    Name P-channel MOSFET

    In the body-arrow MOSFET convention used here, the arrow points toward the channel for N-channel and away for P-channel. Other MOSFET symbol forms place the arrow differently.
