FOD4216SV

Triac, SCR Output Optoisolators Overview

The FOD4216SV is a random phase triac output optocoupler manufactured by onsemi, featuring an infrared emitting diode coupled to a hybrid random phase triac. It provides 5000 Vrms insulation voltage and supports a maximum continuous output current of 300 mA with an off-state output voltage (VDRM) of 600 V. The device operates within a temperature range of -55°C to +100°C, has a forward current of 30 mA, and a forward voltage of 1.28 V. Power dissipation is rated at 500 mW, with a maximum trigger current of 1.3 mA and a maximum turn-on time of 60 µs. It is housed in a 6-SMD package.

Triac, SCR Output Optoisolators Feature Summary

• High isolation voltage capability of 5000 Vrms
• Hybrid construction combining infrared LED with triac

Triac, SCR Output Optoisolators Applications

• Industrial motor control systems
• Solid state relay applications
• Power supply switching circuits

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix SV against the official onsemi datasheet to confirm the SMD-DIP-6 package configuration and bulk packaging details. Ensure that the random phase characteristic aligns with the circuit requirements, as zero-crossing detection is not included. Cross-reference the 600 V off-state voltage rating with the load conditions to prevent overvoltage failure during operation.

Triac, SCR Output Optoisolators Selection Notes

Select this component when snubberless triac driving is required without zero-crossing synchronization. The 600 V blocking voltage suits standard AC line applications. Consider the 300 mA continuous current limit for load sizing. The wide operating temperature range supports harsh industrial environments. Verify thermal management needs given the 500 mW power dissipation rating in the compact surface mount package.

Triac, SCR Output Optoisolators Part Context

The FOD4216SV belongs to the FOD4216 series of Triac & SCR Output Optocouplers from onsemi. This series includes related devices such as the FOD4218, which offers higher voltage ratings. These components are categorized under signal isolation and control solutions, specifically designed for interfacing low-voltage control circuits with high-power AC loads while maintaining electrical safety through galvanic isolation.

Triac, SCR Output Optoisolators Replacement Considerations

The FOD4218 is a confirmed substitute within the same family, offering identical functional characteristics but with an increased off-state output voltage of 800 V compared to the 600 V of the FOD4216SV. Both share the same pinout and package type.
