摘要
本文具体描述了锥形槽状光敏门极结构光控双向晶闸管的设计思想，介绍了该新型结构器件的关键的生产工艺，并对器件的触发特性进行了较深入的理论研究．研制成功的直径为３０ｍｍ，电流容量为２００Ａ，耐压为１２００Ｖ；的光控双向晶闸管的最小光触发功率小于１３ｍｗ，通态峰值压降小于１．５Ｖ，换向ｄｖ／ｄｔ耐量大于１００Ｖ／μｓ，换向ｄｉ／ｄｔ耐量大于５０Ａ／μｓ．
Abstract A design idea of a new light triggered triac structure with a center coneshaped groove light sensitive gate is described,and some key manufacturing techniques of this device are presented.Theoretical studies on the light trigger characteristic have also been done.A 200A,1200V,30mm dia.light triggered triac has been developed.The device has a minimum light triggering power of less than 13mW,on-state voltage of less than 1.5V,commutating dv/dt capability of more than 100V/μs and commutating di/dt capability of more than 50A/μs.
