a component similar to a semiconductor diode but having in addition a gate connection by which the component, normally non-conducting, can be triggered into conduction
a controlled rectifier where the uni-directional current flow from the anode to the cathode is initiated by a small signal current from the gate to the cathode
a four junction (pnpn from the top down I think) device
a semiconductor device acting as an on-off switch triggered by a signal of very small power
a semiconductor device also known as a silicon controlled rectifier (SCR)
a semiconductor device that can be turned on via a gate signal
a semiconductor switch that is used as a gate circuit
Any of a group of solid-state controlling devices. These devices are referred to as TRIACs, SCRs and DIACs.
A power semiconductor device with three terminals called the gate, cathode and anode. Its state becomes conductive (ON) or blocking (OFF) depending on the behavior of these terminals.
A solid-state switching device for semiconductors to convert AC current in one of two directions controlled by an electrode.
Also known as a silicon-controlled rectifier (SCR) is a three-terminal semiconductor. For more information, Click Here .
a type of semiconductor device where 4 layers form 3 PN junctions. Thyristors are very efficient devices for switching large AC signals but latch-on until the signal passes through zero making them unsuitable for DC switching.
(see also SCR) a component like a diode, but will not conduct until a voltage is applied to its third terminal known as the "gate."
A class of four-layer semiconductor devices. Devices designed specifically for high-power switching applications
A term used to classify all four layer semiconductot devices. SCRs and triacs are examples of thyristors.
The thyristor is a solid-state semiconductor device with four layers of alternating N and P-type material. They act as a switch, conducting when their gate receives a current pulse, and continue to conduct for as long as they are forward biased.
