a solid-state semiconductor device with four layers of
alternating P and N-type materials. Some sources define
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 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 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
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) Application:we are one professional
