VOT8026AB-VT2

Overview

The VOT8026AB-VT2 is a high-speed optocoupler manufactured by Vishay Semiconductor Opto Division. It features a single channel with a Triac output and an integrated zero-crossing detection circuit. The device provides electrical isolation of 5300Vrms and supports an on-state current of up to 100 mA. It operates within a temperature range of -55°C to 110°C and is housed in a surface-mount package.

Feature Summary

• Integrated zero-voltage crossing detector for precise AC switching
• High static dV/dt immunity of 1000 V/µs
• Surface-mount packaging for space-efficient designs

Applications

• Solid-state relays
• AC motor control circuits
• Industrial automation systems

Procurement Notes

Verify the specific suffix 'VT2' against official Vishay documentation to confirm tape-and-reel packaging specifications. Ensure the 5300Vrms isolation rating aligns with your safety requirements. Cross-reference the RoHS compliance status with the latest manufacturer declarations before finalizing procurement orders.

Selection Notes

Select this component when zero-crossing functionality is required to minimize electromagnetic interference during AC load switching. The high dV/dt rating makes it suitable for noisy industrial environments. Compare the 100 mA on-state current capability against load requirements to ensure adequate margin for operation.

Part Context

This part belongs to the VOT8xxx series of optotriacs from Vishay, designed for general-purpose AC power control applications. The series emphasizes high reliability and compact form factors. The VOT8026AB variant specifically integrates zero-crossing detection, distinguishing it from standard optotriacs that require external timing circuits for soft-start capabilities.

Replacement Considerations

The VOT8024AB-VT2 is a documented substitute within the same product family, offering similar characteristics with potentially different trigger sensitivities.
