FOD410V

Triac, SCR Output Optoisolators Overview

The FOD410V is a Triac and SCR output optocoupler featuring an infrared LED coupled to a hybrid triac composed of two back-to-back SCRs. It provides zero-voltage crossing switching with a peak on-state current of 300 mA and a blocking voltage of -600 V. The device offers high static dv/dt immunity of 10,000 V/s and a trigger current of -2 mA. It operates within a temperature range of -55°C to +100°C and includes UL1577 certification for 5,000 V AC RMS isolation.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'V' corresponds to the required packaging configuration and regional compliance standards. Confirm that the 6-pin DIP through-hole package aligns with the target PCB layout constraints. Ensure the -600 V blocking voltage rating meets the maximum reverse voltage requirements of the controlled load. Validate that the operating temperature range covers the intended environmental conditions.

Triac, SCR Output Optoisolators Selection Notes

Select this component when snubberless operation is required to minimize passive component count. Choose the FOD410V for applications needing reliable zero-crossing detection at 300 mA loads. Consider the -600 V blocking voltage limit for medium voltage AC lines. Opt for this part over higher voltage variants if cost efficiency is prioritized without sacrificing isolation performance.

Triac, SCR Output Optoisolators Part Context

The FOD410V belongs to the FOD410 series of Triac and SCR output optocouplers manufactured by onsemi. This family utilizes a hybrid triac technology combining two anti-parallel SCRs for robust switching. The series shares common architectural features but varies in blocking voltage ratings and trigger sensitivity specifications across different model numbers.

Triac, SCR Output Optoisolators Replacement Considerations

FOD4108 serves as a substitute offering an increased blocking voltage of -800 V while maintaining similar functional characteristics.
