BT169D IC TO92 THYRISTOR 400V 0. 8A BT169D

Product Overview

The BT169D is a planar passivated Silicon Controlled Rectifier (SCR) designed with a highly sensitive gate. It is housed in a compact SOT54 (TO-92) plastic package and is specifically engineered to interface directly with microcontrollers, logic ICs, and other low-power gate trigger circuits. This device is widely implemented in application environments such as ignition circuits, lighting ballasts, protection circuits, and switched-mode power supplies.
