VO2223A-X007T

Triac, SCR Output Optoisolators Overview

The VO2223A-X007T is a power phototriac output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an 8-SMD surface-mount package with a 5300Vrms isolation voltage and operates within a temperature range of -40°C to +85°C. The device supports a maximum continuous output current of 1 A and a peak off-state voltage of 600 V. Electrical characteristics include a typical forward voltage of 1.4 V, a maximum DC forward current of 50 mA, and a maximum trigger current of 10 mA. It lacks zero-crossing circuitry and provides a minimum static dV/dt of 210 V/µs.

Triac, SCR Output Optoisolators Feature Summary

• Provides high-voltage electrical isolation between control circuits and power triacs using a non-zero-crossing design for precise phase-angle control.
• Integrates a gallium arsenide infrared LED emitter with a sensitive silicon gate power phototriac for efficient triggering.
• Utilizes an 8-SMD鸥翼 (gull-wing) surface-mount package to facilitate automated assembly in compact designs.
