---- Free buffer three quadrant triac series features: advanced glass passivation and polysilicon double protection, low on-state voltage drop SCR BTA140, high junction temperature, high noise immunity, free buffer circuits, high reliability Sexual and stability through ROSH certification application: Mainly for dimming, thermostats SCR BTA225, electronic oven, washing machine, air conditioning, soybean milk, curlers, welcome home, drinking fountains SCR BTA312, lawn mowers, 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 is controlled referred to as silicon rectifier elements, is a four-story structure with a high-power semiconductor devices 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, mostly 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. Single SCR, triac discrimination: first one of the two test poles, if positive and negative test pointer not moving (R × 1 block), may be A, K or G, A pole (one-way controllable silicon) may also be T2, T1 or T2, G pole (for triac). If one has a measurement instructions for tens to hundreds of Europe, it certainly is way thyristor. And a red pen for the connected K-pole, black pen then for G pole, and the rest is the A pole. If the positive and negative test instructions are tens to hundreds of Europe, certainly for the triac. Then dial knob to R × 1 or R × 10 block retest, which must have a resistance slightly, slightly larger than a red pen is connected to G pole, black pen connects to T1 pole, the rest is extremely T2 .
