FOD410SV

Triac, SCR Output Optoisolators Overview

The FOD410SV is a snubberless triac driver optocoupler featuring an infrared LED coupled to a hybrid triac output. It provides zero-crossing detection for AC power control, triggering at voltage peaks to minimize electromagnetic interference. The device offers high dv/dt immunity of 10,000 V/s and supports peak currents up to 300 mA. It operates within a temperature range of -55°C to +100°C and includes UL and VDE safety certifications for reinforced insulation.

Triac, SCR Output Optoisolators Feature Summary

• Snubberless design eliminates external components by integrating zero-crossing detection
• High static dv/dt rating ensures stable operation against rapid voltage transients
• Integrated hybrid triac output simplifies circuit layout and reduces board space
• Compliant with international safety standards including UL1577 and DIN EN/IEC60747-5-5

Triac, SCR Output Optoisolators Applications

• Solid-state relays requiring snubberless triac driving
• AC motor speed control systems
• Lighting dimmer circuits
• Heater control modules

Triac, SCR Output Optoisolators Procurement Notes

Verify the suffix SV indicates the surface-mount package variant distinct from through-hole versions. Confirm RoHS compliance status and specific reel packaging requirements with the supplier. Ensure the ordering part number matches the required pin configuration and isolation voltage ratings for your specific application design.

Triac, SCR Output Optoisolators Selection Notes

Select this component when snubberless operation is required to reduce bill of materials cost. The zero-crossing feature is essential for minimizing electrical noise in sensitive environments. Verify that the 600V blocking voltage meets the peak line voltage requirements of the target AC system.

Triac, SCR Output Optoisolators Part Context

This device belongs to the FOD410/FOD411 series of triac drivers. It shares functional similarities with FOD4108 but differs in package type and specific voltage ratings. The SV suffix denotes a surface-mount DIP-compatible package suitable for automated assembly processes.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes include FOD410 (through-hole) or IL410-X017 (similar isolation). Verify pinout compatibility and ensure the replacement maintains the same zero-crossing behavior and dv/dt immunity levels.
