VO4254D

Overview

The VO4254D is a non-zero-crossing photo-triac optocoupler manufactured by Vishay Semiconductor Opto Division. It features a single channel with an isolation voltage of 5300 Vrms. The device supports a maximum continuous output current of 300 mA and a peak repetitive off-state voltage (VDRM) of 400 V. Key electrical parameters include a forward current (If) of 60 mA, a forward voltage (Vf) of 1.2 V, and a power dissipation (Pd) of 600 mW. The maximum trigger current is specified at 2 mA. Operating temperatures range from -55°C to +100°C. The component is housed in a DIP-6 package for through-hole mounting.

Feature Summary

Non-zero-crossing triac output design for phase-angle control applications
High insulation voltage capability of 5300 Vrms for robust circuit isolation
Through-hole DIP-6 packaging suitable for standard PCB assembly

Applications

Solid-state relay circuits
Motor speed control systems
Lighting dimmer controls

Procurement Notes

Verify availability status carefully as the VO4254D is listed as obsolete or discontinued by the manufacturer. Check for end-of-life notifications or production discontinuance notices before finalizing designs. Sourcing may be limited to distributor surplus or secondary markets. Confirm RoHS compliance details directly with suppliers. Ensure substitute components are evaluated for pin compatibility and electrical equivalence prior to procurement.

Selection Notes

Select this component only if non-zero-crossing switching behavior is required for specific phase-control timing. Verify that the 400 V blocking voltage meets the load requirements. Consider the 2 mA trigger current sensitivity for driver interface matching. Evaluate thermal management needs given the 600 mW power dissipation limit. Confirm that the DIP-6 package fits the mechanical constraints of the target enclosure.

Part Context

This part belongs to the Vishay VO425x series of triac output optocouplers. These devices are designed for general-purpose AC load switching where zero-crossing detection is not necessary. The series typically includes variants with different voltage ratings such as the VO4256D and VO4258D. The VO4254D specifically targets lower voltage AC loads compared to higher-rated siblings in the same family.
