the portfolio of triac driver optocouplers from on semiconductor includes a variety of triac driver optocoupler devices that function like a triac, interfacing between electronic controls and power triacs to control resistive and inductive loads. they consist of a gallium arsenide (gaas) infrared emitting diode coupled to a light-activated silicon bilateral switch, which functions like a triac. the ideal performance characteristics of the portfolio include excellent ift stability (ir emitting diode has low degradation), 300ma on-state current, zero-voltage crossing, high blocking voltage, high trigger sensitivity, and high static dv/dt (10,000v/µs). the devices achieve the following safety and regulatory approvals: ul1577, 4,170 vacrms for 1 minute, vde, fimko, c-ul, and din en/iec60747-5-5. applications include consumer appliances, industrial motor controls, industrial controls, traffic lights, vending machines, solid state relays, lamp ballasts, solenoid / valve controls, static ac power switch, incandescent lamp dimmers, lighting controls, ac motor starters, and static power switches.
