FOD4216SDV

Triac, SCR Output Optoisolators Overview

The FOD4216SDV is a single-channel Triac output optocoupler from onsemi, designed for snubberless random phase triac control applications. It features a PhotoTriac output capable of handling a maximum continuous output current of 300 mA and a repetitive peak off-state voltage (VDRM) of 600 V. The device provides robust electrical isolation with an insulation voltage rating of 5000 Vrms. Key electrical parameters include a maximum forward current (If) of 30 mA, a typical forward voltage (Vf) of 1.28 V, and a maximum turn-on time of 60 µs. It operates within a temperature range of -55°C to +100°C and is housed in a 6-SMD package.

Triac, SCR Output Optoisolators Feature Summary

• Snubberless operation enables direct triggering of random phase triacs without external RC snubber networks.
• High static dV/dt immunity minimizes false triggering during rapid voltage transients.
• Integrated PhotoTriac output provides reliable switching for AC load control applications.

Triac, SCR Output Optoisolators Applications

• Solid state relays (SSRs)
• Motor speed controllers
• Lighting dimmers

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'SDV' to confirm the surface mount 6-SMD package configuration and tape-and-reel or cut-tape availability. Ensure compliance with RoHS standards and check for UL, VDE, and cUL certifications required for end-product safety approvals. Confirm operating temperature range requirements match the -55°C to +100°C specification before finalizing component selection for industrial environments.

Triac, SCR Output Optoisolators Selection Notes

Select this component when snubberless triac driving is required to reduce bill-of-materials count and improve reliability. The 600 V VDRM rating suits general-purpose AC line voltages. Consider the 5000 Vrms isolation barrier for high-voltage separation needs. Compare trigger current specifications against microcontroller GPIO capabilities to ensure adequate drive strength without excessive current draw.
