FOD410S

Triac, SCR Output Optoisolators Overview

The FOD410S is a 6-pin DIP high dv/dt zero-crossing triac driver from onsemi. It integrates an infrared LED with a hybrid triac composed of two back-to-back SCRs to drive discrete triacs. Key electrical parameters include a peak on-state current of 300 mA and a blocking voltage of -600 V. The device features a static dv/dt rating of 10,000 V/s and a trigger current of -2 mA. It offers UL1577 certification for 5,000 V AC RMS isolation and complies with DIN EN/IEC60747-5-5 standards. Operating temperature ranges from -55°C to +100°C.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'S' indicates surface mount or tape-and-reel packaging if required, as standard FOD410 variants may differ in package type. Confirm RoHS compliance status for environmental regulations. Ensure the -600 V blocking voltage meets circuit requirements rather than the higher -800 V variant. Validate insulation clearance distances against local safety standards for the intended installation classification.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing functionality is critical to minimize electromagnetic interference during AC switching. The -600 V blocking voltage suits lower voltage AC lines compared to the -800 V FOD4108/FOD4118 series. Consider the 300 mA peak current limit for driving discrete triacs; higher current needs may require external amplification. The 6-pin DIP package facilitates through-hole prototyping and assembly.

Triac, SCR Output Optoisolators Part Context

The FOD410S belongs to the FOD410/FOD4108/FOD4116/FOD4118 family of high dv/dt zero-crossing triac drivers. These devices are designed to replace complex discrete optocoupler and SCR combinations. The family shares similar functional architectures but varies in blocking voltage and trigger sensitivity. The FOD410S specifically targets applications requiring robust isolation and noise immunity in AC control environments.

Triac, SCR Output Optoisolators Replacement Considerations

FOD4108 serves as a direct substitute with increased -800 V blocking voltage. FOD4116 and FOD4118 offer improved trigger sensitivity (-1.3 mA) due to efficient IR LEDs. Verify pin compatibility and package dimensions before substitution. Ensure the replacement part's dv/dt rating matches the application's noise environment.
