5SHX1445H0001 3BHL000391P0101 semiconductor thyristor module

Product details:

5SHX1445H0001 3BHL000391P0101 thyristor, is short for thyristor rectifier, is a kind of

high-power semiconductor device with three PN junction structure of four layers, also known

as the thyristor. It has the characteristics of small size, relatively simple structure and strong

function. It is one of the most commonly used semiconductor devices. The device is widely used in

various electronic equipment and electronic products, mostly used for controllable rectification, inverter,

frequency conversion, voltage regulation, contactless switch, etc. Dimming lights, speed fans, air conditioners,

TV sets, refrigerators, washing machines, cameras, combination sound, audio and optical circuits, timing5SHX1445H0001

controllers, toy devices, radio remote control, cameras and industrial control are a large number of thyristor devices.
Thyristor in the circuit can realize AC contactless control, with small current control of large current, and not

like the relay control spark generation, and fast action, long life, good reliability. In speed regulation, dimming,

voltage regulation, temperature regulation and other various control circuits have its figure.

The transistor four layers work like two transistors, they are connected together (as shown below), the output of

one forms the input of the other, and the gate acts as a kind of “starting motor” to activate them.

A single thyristor (SCR) is a combination of a pnp transistor (Q 1) and an npn transistor (Q 2). Here, Q1’s

emitter is the anode terminal of the SCR, and Q2’s emitter is its cathode. In addition, the base of Q1 is connected

to Q2’s collector, the collector of Q1 is connected to Q’s base, and the gate terminal of the thyristor is also connected to Q2’s base.
