---- Free buffer three quadrant triac series features: advanced glass passivation and polysilicon double protection, low on-state voltage drop, high junction temperature SCR, high anti-interference ability, free buffer circuits, high reliability and stability, through ROSH certification application: Mainly for dimming, thermostats, electronic oven triac, washing machines, air conditioners, soybean milk, curlers, welcome home, drinking fountains, lawn machines, shredders, mahjong machines, power tools and other appliances control circuit, and AC phase control, drive and solid-state relays, and other circuits. Dongguan factory triac spot BTA80-800B wholesale authentic agent of the triode thyristor, thyristor rectifier element is referred to as It is a four-layer structure of power semiconductor devices having three PN junction, also known as thyristors. With a small, relatively simple structure, function, and other characteristics, is one of the more commonly used semiconductor devices. The device is widely used in various electronic devices and electronic products without insulation SCR, usually used as a controlled rectifier, inverter, frequency, voltage, non-contact switches. Household Appliances dimming lights, speed fans, air conditioners, televisions, refrigerators, washing machines, cameras, hi-fi, sound and light circuit, timing controller, toys device, radio-controlled, camera and so widely used in industrial control SCR devices. TYN812 12A, 800V four-way thyristor structure P1N1P2N2 structure thyristor SCR shape no matter how they die is P-type and N-type silicon silicon composition. See Figure 1. It has three a PN junction (J1, J2, J3) SCR s6025, from P1 layer J1 structure leads to the anode A, drawn from the N2 layer cathode K, leads from the P2 layer control electrode G, so it is a four-three-terminal semiconductor devices.
