Triac, SCR Output Optoisolators datasheet and documents for FOD4108SD

FOD4108SD

Triac, SCR Output Optoisolators Overview

The FOD4108SD is a high dv/dt zero-crossing triac driver optocoupler from onsemi, designed for snubless triac drive applications. It features a black package and provides galvanic isolation with a 5000Vrms rating. The device operates within a temperature range of -55°C to 100°C and utilizes a 6-SMD gull wing surface mount package. It integrates an LED input side with a triac output stage, enabling precise phase control in AC power switching systems without requiring external snubber circuits.
