Manufacturer: Vishay Semiconductor Opto Division

Categories: Triac, SCR Output Optoisolators

Quality Control: Learn More

The Vishay Semiconductor Opto Division VO4257D is a single-channel optoisolator featuring a Triac output. This component provides a high isolation voltage of 5300Vrms and is designed for through-hole mounting in a 6-DIP package. It offers a robust static dV/dt of 5kV/µs and an off-state voltage capability of 700V. The device requires a maximum DC forward current (If) of 60mA for its internal LED and has a maximum LED trigger current (Ift) of 1.6mA. The Triac output can handle a maximum RMS on-state current (It (RMS)) of 300mA. Operating across a temperature range of -55°C to 100°C, the VO4257D is suitable for applications in industrial control, power supplies, and solid-state relays. It holds approvals from BSI, cUR, FIMKO, and UR.
