Introduction:
A thyristor/SCR is a solid-state semiconductor device with four layers of alternating P and N-type materials. Some sources define a silicon-controlled rectifier (SCR) and thyristor/SCR as synonymous.
It acts exclusively as a bistable switch, conducting when the gate receives a current trigger and continuing to conduct while the voltage across the device is not reversed (forward-biased). A three-lead thyristor/SCR is designed to control the larger current of its two leads by combining that current with the smaller current of its other lead, known as its control lead. In contrast, a two-lead thyristor/SCR is designed to switch on if the potential difference between its leads is sufficiently large (breakdown voltage).
The first thyristor/SCR devices were released commercially in 1956. Because thyristor/SCRs can control a relatively large amount of power and voltage with a small device, they find wide application in control of electric power, ranging from light dimmers and electric motor speed control to high-voltage direct-current power transmission. thyristor/SCRs may be used in power-switching circuits, relay-replacement circuits, inverter circuits, oscillator circuits, level-detector circuits, chopper circuits, light-dimming circuits, low-cost timer circuits, logic circuits, speed-control circuits, phase-control circuits, etc. Originally, thyristor/SCRs relied only on a current reversal to turn them off, making them difficult to apply for direct current; newer device types can be turned on and off through the control gate signal. The latter is known as a gate turn-off thyristor/SCR, or GTO thyristor/SCR. A thyristor/SCR is not a proportional device like a transistor. In other words, a thyristor/SCR can only be fully on or off, while a transistor can lie in between on and off states. This makes a thyristor/SCR unsuitable as an analog amplifier, but useful as a switch.
Classification:
thyristor/SCR according to the shutoff, conduction and control methods can be divided into ordinary thyristor/SCR (SCR), bidirectional thyristor/SCR (TRIAC), inverse thyristor/SCR (RCT), gate turn off thyristor/SCR (decision), BTG temperature control of thyristor/SCR, thyristor/SCR (TT abroad, TTS domestic) and optically controlled thyristor/SCR (LTT), etc.
The thyristor/SCR can be divided into two polar thyristor/SCR, triode thyristor/SCR, and quadrupole thyristor/SCR according to its pins and polarity.
The thyristor/SCR can be divided into three types: metal packaging thyristor/SCR, plastic sealing thyristor/SCR, and ceramic packaging thyristor/SCR.
Among them, metal packaging thyristor/SCR is divided into a bolt shape, plate shape, round shell, and so on. The laminated thyristor/SCR is divided into two kinds: strip fin and no heat sink.
The thyristor/SCR can be divided into three types: high-power thyristor/SCR, medium power thyristor/SCR, and small power thyristor/SCR according to the current capacity.
In general, the large-power thyristor/SCR adopts a ceramic package, while the medium and small power thyristor/SCR is mostly sealed or metal encapsulated.
thyristor/SCR speed according to the cut-off can be divided into ordinary thyristor/SCR and fast thyristor/SCR, fast thyristor/SCR include all specially designed for rapid application of thyristor/SCR, have regular fast thyristor/SCR and working in a higher frequency of high-frequency thyristor/SCR, respectively applied to 400 Hz and above 10 kHz chopping or inverter circuits.
(note: high frequency does not equal fast thyristor/SCR)
