FOD420SDV

Triac, SCR Output Optoisolators Overview

The FOD420SDV is a random phase triac snubberless optocoupler manufactured by onsemi. It features a single channel phototriac output with an isolation voltage of 5000 Vrms. The device operates within a temperature range of -55°C to +100°C and supports a maximum forward current of 30 mA. Key electrical parameters include a peak repetitive off-state voltage (VDRM) of 600 V, a typical turn-on time of 60 µs, and a maximum trigger current of 2 mA. The component is housed in a 6-pin SMD-DIP package.

Triac, SCR Output Optoisolators Feature Summary

• Snubberless design for direct triac triggering without external RC networks
• High dv/dt noise immunity for reliable operation in noisy environments
• Random phase output suitable for AC power control applications

Triac, SCR Output Optoisolators Applications

• Solid state relays
• AC motor speed control
• Lighting dimmers

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'SDV' corresponds to the required tape and reel packaging configuration. Confirm that the 6-pin SMD-DIP footprint matches the target PCB layout. Ensure the 5000 Vrms isolation rating meets the safety requirements of the final equipment design. Check for RoHS compliance status if restricted substances are a constraint.

Triac, SCR Output Optoisolators Selection Notes

Select this component when snubberless triac driving is required to reduce bill of materials count. The high dv/dt capability makes it suitable for industrial environments with significant electrical noise. Consider the 600 V blocking voltage for standard AC line applications. Verify thermal dissipation limits given the 500 mW power dissipation rating.

Triac, SCR Output Optoisolators Part Context

This part belongs to the FOD420 series of triac driver optocouplers. It is designed to replace discrete triac driver circuits by integrating the LED and phototriac in a single package. The series offers high reliability for AC switching applications requiring galvanic isolation between control and load sides.

Triac, SCR Output Optoisolators Replacement Considerations

Check datasheets for equivalent parts from other manufacturers offering similar snubberless triac drivers. Verify pinout compatibility before substitution. Ensure replacement components meet the same 5000 Vrms isolation and 600 V blocking voltage specifications.
