VO2223

Triac, SCR Output Optoisolators Overview

The VO2223 is a power phototriac optocoupler featuring an integrated power TRIAC output driven by an infrared LED. It provides galvanic isolation in an 8-pin DIP package. Key electrical parameters include a 5300 Vrms isolation voltage, 1 A RMS on-state current, and 600 V blocking voltage. The device operates without a zero-crossing circuit, supporting a forward current of 50 mA and a trigger current of 10 mA. It functions within a temperature range of -40°C to +85°C.

Triac, SCR Output Optoisolators Feature Summary

• Integrates an infrared emitting diode with a high-power phototriac for robust load switching
• Provides high-voltage galvanic isolation between input control circuits and output loads
• Designed for random-phase triggering applications requiring fast response times

Triac, SCR Output Optoisolators Applications

• Solid-state relays for AC load control
• Motor speed controllers
• Lighting dimmer circuits

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., DIP-8 vs. SMD) against the datasheet to ensure correct package type. Confirm RoHS compliance status and check for recent PCN notifications regarding leadframe or mold material changes. Ensure the selected variant matches the required isolation voltage and current ratings for the target application.

Triac, SCR Output Optoisolators Selection Notes

Select this component for applications requiring high isolation voltage and significant load current handling. The absence of a zero-crossing feature makes it suitable for phase-control applications where precise timing is necessary. Verify that the thermal management supports the 1.2 W power dissipation rating under operating conditions.

Triac, SCR Output Optoisolators Part Context

This component belongs to Vishay's VO2223 series of power phototriac optocouplers. It serves as a foundational device for industrial AC switching solutions, offering a balance of high isolation capability and moderate current handling in a standard through-hole package format widely used in legacy and new designs.

Triac, SCR Output Optoisolators Replacement Considerations

Check for direct pin-compatible alternatives within the same series, such as the VO2223A or VO2223B variants, which may offer updated packaging or minor parameter adjustments. Ensure any substitute maintains the 5300 Vrms isolation rating and 1 A current capacity.
