Transistor Terms

TRANSISTOR. A semiconductor device with three or more elements, Emitter, Base, Collector. A semiconductor device capable of providing power amplification. Also called a Bipolar Junction Transistor [BJT], [BJT Manufacturers]

BJT

Alpha. The emitter-to-collector current gain in a common-base circuit of a transistor.

Base: A region which lies between an emitter and collector of a transistor and into which minority carriers are injected.

Collector: A region through which a primary flow of charge carriers leaves the base.

Emitter: A region from which charge carriers that are minority carriers in the base are injected into the base.

Saturation: A base current and a collector current condition resulting in a forward-biased collector junction.

COMMON BASE. A transistor circuit in which the base electrode is the common element to both input and output circuits.

COMMON COLLECTOR. A transistor circuit configuration in which the collector is the element common to both the input and the output circuits.

COMMON EMITTER. A circuit configuration in which the emitter of a transistor is the element common to both the input and the output circuits.

Darlington. Darlington Amplifier, a double emitter follower.

Darlington Amplifier

h_fb, h_fc, h_fe: Small signal short circuit forward current transfer ratio (common base, common collector, common emitter)

h_ib, h_ic, h_ie: Small signal short circuit input impedance (common base, common collector, common emitter)

V_BB: Base supply voltage

V_BE: Base to Emitter supply voltage

V_CB: Collector to Base supply voltage

V_CC: Collector supply voltage

V_CE: Collector to Emitter supply voltage
