FODM3083R1 is listed in the Triac, SCR Output Optoisolators range at ChipApex. The manufacturer field lists onsemi. Its product description is OPTOISOLTR 3.75KV TRIAC 1CH 4SMD. Review the specifications below when checking this part for your BOM.
The FODM3083R1 is a single-channel Triac output optocoupler from onsemi, housed in a 4-SMD Miniflat package. It features an integrated zero-crossing detection circuit for precise AC load switching. Key electrical parameters include a maximum forward voltage of 1.5V, a peak forward current of 60mA, and an isolation voltage of 3750Vrms. The device supports a blocking voltage of 800V and a continuous output current of 70mA. It operates within a temperature range of -40°C to 100°C and includes a minimum static dV/dt rating of 600V/µs.
Verify the specific suffix R1 against official datasheets to confirm tape-and-reel packaging and obsolete status. Cross-reference manufacturer documentation for lead times and availability constraints. Ensure compliance with RoHS and REACH standards as specified in the component declaration. Confirm that the 4-SMD gull-wing footprint matches the target PCB layout requirements before procurement.
Select this component when high-voltage isolation and zero-crossing functionality are required for AC loads. The 800V blocking voltage suits general industrial applications. Consider the 600V/µs static dV/dt rating for noise immunity. Evaluate the Miniflat package dimensions against board space limitations. Compare thermal dissipation characteristics against alternative optocouplers if operating near the upper temperature limit.
This part belongs to the FODM30 series of Triac output optocouplers by onsemi. It provides galvanic isolation for controlling triacs or SCRs in AC power applications. The series is designed for robust performance in industrial environments, offering reliable switching with minimal electromagnetic interference due to the zero-crossing feature.
