Description

General part information

LJ4004D8RP Series

This 4 A High Temperature Triac solid state switch series is designed for AC switching and phase control applications such as motor speed and temperature modulation controls, lighting controls, and static switching relays. Sensitive type devices guarantee gate control in Quadrants I & IV needed for digital control circuitry. Standard type devices normally operate in Quadrants I & III triggered from AC line.
