Genuine original big chip BT137-600E SCR triac thyristor rectifier element is referred to, is a four-layer structure of power semiconductor devices having three PN junctions. Indeed SCR, SCR thyristor rectifier function is not only BTA412Y, it can be used as non-contact switch to quickly turn on or off the circuit SCR BTA212, realize the DC power into AC power inverters, A frequency of the alternating current into alternating current of another frequency, and so on. SCR and other semiconductor devices, as its small size, high efficiency, good stability, working and reliable. It appears, from the weak areas of semiconductor technology into the strong electric field SCR BTA216, become a member of industry, agriculture, transportation, military, scientific research as well as commercial, consumer electronics and other aspects of competing uses. Features ☆ SCR zero-voltage input, current zero resection; after ☆ low power switch is turned on, no external heat sink; ☆ no external series reactor; ☆ input signal and switch optical isolation; ☆ directly with no with the use of reactive compensation controller; ☆ built-in control power, with no external power supply; ☆ has a switching status indicator, capacitance on, the indicator light; ☆ system outage, the switch automatically cut off after the normal power supply, automatic return to work; ☆ anti-interference ability, high EMC protection.
