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)Detailed Photos Application:we are
