Triac thyristor modules radiator (four) by the current capacity classification: SCR can be divided according to the current capacity of high-power thyristor, the power and low-power SCR SCR three. Typically SCR BT136S-600E, power SCR more metal shell package, while medium and small power thyristor is to use more plastic or ceramic package. (E) by off-speed Category: SCR turn-off speed can be divided according to their ordinary SCR and high frequency (fast) SCR. Triac - construction principles Typical products BCMlAM (1A / 600V), BCM3AM (3A / 600V), 2N6075 (4A / 600V), MAC218-10 (8A / 800V) and so on. Power triac mostly used RD91 package. SCR BT137S-600E, SCR, are fertile Electronics Dongguan City is provided by Wal-Electronic Technology Co., Ltd. Dongguan City is Wal-Electronic Technology Co., Ltd.
