VO2223B-X007T

Triac, SCR Output Optoisolators Overview

The VO2223B-X007T is a single-channel Triac and SCR output optocoupler manufactured by Vishay Semiconductor Opto Division. It integrates an AlGaAs LED with a power phototriac in an 8-SMD package. The device provides 5300 Vrms isolation voltage and supports a continuous RMS output current of 1 A at a peak off-state voltage of 600 V. It operates without a zero-crossing circuit, allowing for phase control applications. The component functions within a temperature range of -40°C to +85°C and features a maximum forward current of 50 mA.

Triac, SCR Output Optoisolators Feature Summary

• Integrates an AlGaAs infrared LED emitter with a high-power phototriac detector for efficient optical coupling.
• Provides robust electrical isolation rated at 5300 Vrms between input and output circuits.
• Designed for non-zero-crossing operation to enable precise phase-angle firing control in AC loads.
• Packaged in a compact surface-mount 8-SMD configuration suitable for automated assembly.

Triac, SCR Output Optoisolators Applications

• Solid-state relays (SSRs) requiring high isolation and triac output
• AC motor speed control circuits
• Industrial process control systems

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix X007T confirms the tape-and-reel packaging format required for your manufacturing line. Confirm that the 5300 Vrms isolation rating meets your safety certification requirements. Ensure the 1 A RMS current capacity is sufficient for the intended load. Check that the absence of a zero-crossing feature aligns with your phase-control design needs rather than noise-sensitive switching.

Triac, SCR Output Optoisolators Selection Notes

Select this component when a surface-mount solution is required for AC power switching applications. It is appropriate for designs needing high isolation voltage without the timing constraints of zero-crossing detection. Consider the 8-SMD footprint for space-constrained PCB layouts. Verify that the 600V blocking capability matches the peak line voltage of the application.

Triac, SCR Output Optoisolators Part Context

This part belongs to the Vishay VO2223 series of Triac output optocouplers. The series includes variants such as VO2223A and VO2223B, which differ primarily in packaging and reel specifications. The VO2223B variant specifically denotes the surface-mount construction, distinguishing it from through-hole DIP options within the same functional family.

Triac, SCR Output Optoisolators Replacement Considerations

Publicly confirmed substitute part numbers include VO2223A-X007T and VO2223B-X017T. These alternatives share similar functional characteristics but may differ in packaging quantities or specific mechanical tolerances. Verify pinout compatibility and thermal performance before substitution.
