FODM3053R4V

Triac, SCR Output Optoisolators Overview

The FODM3053R4V is a Triac output optocoupler manufactured by onsemi, designed for AC power control applications. It features a single channel with a PhotoTriac output capable of handling a maximum continuous output current of 70 mA and a peak off-state voltage (VDRM) of 600 V. The device provides high isolation with an insulation voltage of 3750 Vrms. It operates without a zero-crossing circuit, allowing for phase-angle firing control. The component is housed in a 4-SMD Miniflat package with gull-wing leads, suitable for surface mount technology. It supports a forward current of up to 60 mA and functions within a temperature range of -40°C to +100°C.
