WeEn Semiconductors Co., Ltd BT169D,112, Thyristor 400V, 0.5A 0.2mA

A Thyristor is a solid-state semiconductor device with four layers of alternating N and P-type material. They act as bistable switches, conducting when their gate receives a current trigger, and continue to conduct while they are forward biased. Thyristors are synonymous to Silicon-Controlled Rectifier (SCR).

Planar passivated Silicon Controlled Rectifier (SCR) in a SOT78 plastic package intended for use in applications requiring high bidirectional blocking voltage capability, high surge current capability and high thermal cycling performance.
