The BT169D from NXP is a through hole planar passivated silicon controlled rectifier with sensitive gate in a SOT54 (TO-92) plastic package. This SCR is designed to be interfaced directly to microcontrollers, logic ICs and other low power gate trigger circuits. Typical applications of SCR are Ignition circuits, lighting ballasts, protection circuits.
Planar passivated for voltage ruggedness and reliability
Sensitive gate
