OPTOISOLATOR 5.3KV TRIAC 6DIP

Manufacturer: Vishay Semiconductor Opto Division

Categories: Triac, SCR Output Optoisolators

Quality Control: Learn More

Vishay Semiconductor Opto Division VO4257H is a single-channel optoisolator featuring a Triac output. This component provides 5300Vrms isolation and a 700V off-state voltage. It is designed for through-hole mounting in a 6-DIP package and operates across a temperature range of -55°C to 100°C. The device requires a maximum forward current of 60mA and a maximum LED trigger current of 2mA for operation. The Triac output can handle up to 300mA RMS. With a static dV/dt rating of 5kV/µs, this optoisolator is suitable for applications in industrial controls, power switching, and solid-state relays requiring high voltage isolation and robust switching capabilities. Agency approvals include BSI, cUR, FIMKO, and UR.
