FODM3082

Triac, SCR Output Optoisolators Overview

The onsemi FODM3082 is a single-channel Triac and SCR output optocoupler designed for surface mount applications. It features a Miniflat package with four pins, providing robust electrical isolation between input and output circuits. The device incorporates an integrated zero-crossing detection circuit to minimize electromagnetic interference during switching operations. Key electrical specifications include a maximum forward voltage of 1.5V, a maximum DC forward current of 60mA, and a high isolation voltage rating of 3750Vrms. It supports a peak repetitive off-state voltage (VDRM) of 800V and can handle a maximum continuous output current of 70mA. The component operates within a temperature range of -40°C to +100°C.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix variant against the original datasheet requirements, as packaging or tape-and-reel configurations may differ from standard tube quantities. Confirm that the selected part number matches the required insulation voltage and output current ratings for the target application environment. Ensure compliance with RoHS directives if applicable to the manufacturing process.

Triac, SCR Output Optoisolators Selection Notes

Select this component when a compact, surface-mount solution is required for controlling TRIACs or SCRs in AC power applications. The integrated zero-crossing feature makes it suitable for noise-sensitive environments where EMI reduction is critical. Consider the 800V blocking voltage and 70mA output current limits to ensure adequate headroom for the load being driven.

Triac, SCR Output Optoisolators Part Context

The FODM3082 belongs to the broader category of Triac and SCR output optocouplers manufactured by onsemi. It is part of a family of devices designed for industrial and consumer AC power control applications. Similar variants in the series may offer different pin counts or packaging styles, such as the six-pin MOC3082SR2M, but share core functional principles regarding optical isolation and TRIAC triggering.

Triac, SCR Output Optoisolators Replacement Considerations

The FODM3083R2 is identified as a potential replacement option for the FODM3082. Both are Triac and SCR output optocouplers with zero-crossing capabilities and similar voltage ratings. Verify pin compatibility and package dimensions before substitution.
