The L4X8E5 from Littelfuse is a Triac that has been designed for AC switching and phase control applications such as motor speed and temperature modulation controls, lighting controls, and static switching relays. It has a break-over voltage of 400 V and a break-over current of 10 A. This triac guarantees gate control in Quadrants I & IV and can be directly driven by microprocessors or popular optocouplers/isolators. It has glass-passivated junctions for improved electrical isolation along with a low leakage current. This RoHS-compliant triac is available in a through-hole package that measures 8.5 x 2.54 mm.
