VO4257D

Overview

The VO4257D is a non-zero-crossing photo-triac output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a high dV/dt capability and low input current requirements, making it suitable for precise phase-angle control applications. The device provides electrical isolation with an insulation voltage of 5300 Vrms. Key electrical parameters include a maximum forward current (If) of 60 mA, a forward voltage (Vf) of 1.2 V, and power dissipation (Pd) of 600 mW. The output stage supports a peak repetitive off-state voltage (VDRM) of 600 V and a maximum continuous output current of 300 mA. The unit operates within a temperature range of -55°C to +100°C.

Feature Summary

Non-zero-crossing triac output design enables fine and phase-angle independent control
High dV/dt capability ensures reliable operation in noisy environments
Low input current requirement facilitates efficient driving from logic circuits

Applications

Phase-angle control circuits
Solid-state relays
Motor speed control systems

Procurement Notes

Verify the specific ordering suffix against official Vishay documentation to ensure correct packaging and variant selection. Confirm that the component meets required RoHS compliance standards for your region. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when non-zero-crossing switching behavior is required for phase-control applications. Ensure the circuit design accommodates the 600 V off-state voltage rating. Verify that the load current does not exceed the 300 mA continuous limit. Consider the thermal management requirements given the 600 mW power dissipation specification during operation.

Part Context

This component belongs to the Vishay VO425x series of optocouplers, which are designed for general-purpose isolation and switching applications. The series includes variants with different voltage ratings and zero-crossing capabilities. The VO4257D specifically addresses applications requiring immediate response without the delay associated with zero-crossing detection mechanisms.
