VO4254D-X007T

Overview

The VO4254D-X007T is a single-channel photo-triac output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a non-zero-crossing triac output capable of blocking up to 400 V in the off-state and conducting a maximum continuous current of 300 mA. The device provides an isolation voltage of 5300 Vrms and operates within a temperature range of -55°C to +100°C. Packaged in a surface-mount 6-SMD gull-wing configuration, it requires a maximum gate trigger current of 1.6 mA for activation.

Feature Summary

Integrates a high-voltage photo-triac output stage for direct AC load control without zero-crossing detection circuitry.
Provides robust electrical isolation with a rated insulation voltage of 5300 Vrms between input and output circuits.
Designed for surface-mount assembly using a compact 6-SMD gull-wing package suitable for automated manufacturing.

Applications

Solid-state relay (SSR) modules
AC motor speed control circuits
Industrial process control systems

Procurement Notes

Verify the specific suffix X007T corresponds to the required tape-and-reel packaging format. Confirm that the non-zero-crossing characteristic aligns with the application's switching requirements, as this differs from zero-crossing variants. Ensure the 400V blocking voltage meets the peak line voltage specifications of the target AC system.

Selection Notes

Select this component when phase-angle control or random-phase switching of AC loads is required. The non-zero-crossing design allows triggering at any point in the AC cycle, which is essential for dimming applications. Verify that the 300mA output current rating exceeds the maximum load current to ensure reliable operation under thermal stress.

Part Context

This part belongs to the VO425x series of Vishay photo-triac optocouplers. These devices are engineered for general-purpose AC switching applications requiring galvanic isolation. The series offers various voltage ratings and packaging options to accommodate different board space and isolation voltage constraints in industrial and consumer electronics designs.
