VOT8025AB-T

Overview

The VOT8025AB-T is a single-channel Triac output optoisolator manufactured by Vishay Semiconductor Opto Division. It features an internal zero-crossing detection circuit for low electromagnetic interference switching. The device provides 5300Vrms isolation voltage and supports an on-state current of 100mA with a peak off-state voltage of 800V. It operates within a temperature range of -40°C to +110°C and utilizes a 6-SMD surface-mount package.

Feature Summary

• Integrated zero-crossing detection circuitry for noise-free AC load control
• High static dV/dt rating of 1000 V/µs for improved noise immunity
• High input sensitivity allowing direct interface with standard logic families

Applications

• Solid state relays (SSR)
• AC motor speed controllers
• Lighting dimmer circuits

Procurement Notes

Verify the specific suffix 'T' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 6-SMD footprint matches the target PCB layout dimensions. Ensure compliance with RoHS3 directives if environmental regulations apply to the final product deployment.

Selection Notes

Select this component when zero-crossing functionality is mandatory to minimize electrical noise during AC switching events. The 100mA output current capability suits low-power resistive loads. Consider the 6-pin SMD package constraints against available board space and thermal dissipation requirements for the specific application environment.

Part Context

This part belongs to the VOT8025A family, which includes variants such as VOT8025AB-VT and VOT8025AD. These devices share the same core optoelectronic architecture but differ in packaging styles and reel quantities. The VOT8025AB-T specifically denotes the surface-mount variant optimized for high-volume manufacturing integration.

Replacement Considerations

Direct substitutes include VOT8025AB-VT and VOT8025AB-T2 from the same manufacturer series.
