anode terminal (A, a) (1) (general)

The terminal connected to the p‑type region of the p‑n junction or, when two or more p‑n junctions are connected in series and have the same polarity, to the extreme p‑type region.

NOTE 1    See note to “anode”.

NOTE 2    This definition does not apply to current-regulator diodes.

NOTE 3    For voltage-reference diodes, any temperature-compensating diodes that may be included shall be ignored in the determination of the anode terminal.

NOTE 4    For unidirectional blocking or low-capacitance ABDs, any rectifier diode(s) that may be included are ignored in the determination of the anode terminal.

(2) (of a current-regulator diode): The terminal to which current flows from the external circuit when the diode is biased to operate as a current regulator.

(3) (of a unidirectional diode thyristor): The terminal to which the current flows from the external circuit when the thyristor is in the on state.

(4) (of a unidirectional triode thyristor): The main terminal to which the principal current flows from the circuit being controlled when the thyristor is in the on state.

NOTE A second anode terminal may be provided for connecting to the control circuit of an n‑gate thyristor.
