The onsemi FODM3021R4 is a high-performance optocoupler featuring a Triac driver output. This component provides 3750Vrms isolation and is designed for controlling Triac loads in demanding applications. Key specifications include a maximum DC forward current of 60mA for the input LED and a typical holding current of 300µA for the output. The device requires a maximum LED trigger current (Ift) of 15mA and handles an RMS on-state current of up to 70mA. It operates across a temperature range of -40°C to 100°C. The FODM3021R4 is housed in a 4-SMD gull wing package, suitable for surface mounting. This optocoupler is commonly utilized in industrial automation, solid-state relay designs, and power control systems where reliable isolation and efficient Triac switching are critical. The device offers a typical forward voltage of 1.2V and an off-state voltage rating of 400V, with a typical static dV/dt of 10V/µs. It is available in Tape & Reel packaging and carries BSI, CSA, and UL approvals.
