Thyristors - TRIACs

BTA20-700BWRG Application Field and Working Principle

Thyristors are a type of semiconductor devices with special characteristics, designed to serve as switches, rectifiers, phase control and other functions. TRIACs, in particular, are a type of thyristors with two anode terminals, known as "alternating current electronic switches", used for applications involving alternating current signals.

The BTA20-700BWRG is a general-purpose, industrial-grade TRIAC, designed for applications that require a simple, low-power and yet reliable alternative to traditional solid-state switches. It features a TO- 220AB package and can be used in a variety of domestic and industrial applications, such as AC dimming light fixtures, solid-state relays, switch-mode power supplies, and temperature controllers. The main features of the BTA20-700BWRG include a blocked voltage of 4 volts, an on-state RMS current of 4 amps, a gate trigger current of 0.5 amps and a maximum repetitive peak off-state voltage of 700 volts.

The BTA20-700BWRG works on the principle of a four-layer, three-terminal device, with two anode and two gate terminals. It allows an AC signal to pass through when the gate terminal voltage reaches a certain specified level. The BTA20-700BWRG is enabled by an external signal, which causes an electron flow from the gate terminal to the anode. This causes the device to turn on and the current starts to pass through it. The device then turns off when the gate voltage reaches the off-state voltage level.

The BTA20-700BWRG is suitable for applications with a region where a DC signal is used, such as appliances and systems with highly specific requirements. It is also used in applications which involve power regulatory techniques, such as dimming light fixtures and solid-state relays. In these cases, the BTA20-700BWRG is used to control the current or voltage supplied to the load.

Overall, the BTA20-700BWRG is a reliable, low-power and cost-efficient TRIAC suited for a variety of applications. It is a versatile device, with a blocked voltage of 4 volts, an on-state current of 4 amps, a gate trigger current of 0.5 amps, and a maximum repetitive peak off-state voltage of 700 volts. The device works on the principle of four-layer, three-terminal device, with two anode and two gate terminals, allowing an AC signal to pass through when the gate terminal voltage reaches a certain specified level.
