Overview
The VO4158H-X007T is a surface-mount zero-crossing photo-triac optocoupler manufactured by Vishay Semiconductor Opto Division. It features a single channel with an infrared emitting diode and a triac output, housed in a 6-SMD package. The device provides 5300 Vrms isolation voltage and supports a maximum forward current of 60 mA. It includes an integrated zero-crossing detection circuit to minimize electromagnetic interference during AC switching applications.
Feature Summary
- Integrated zero-crossing detection circuit for low-noise AC power control
- High isolation voltage capability for safe electrical separation
- Surface-mount design optimized for automated assembly processes
Applications
- Solid-state relays for AC load switching
- Motor control circuits requiring phase-angle or zero-crossing triggering
- Industrial automation systems with isolated AC interface requirements
Procurement Notes
Verify the specific suffix X007T corresponds to the required tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the exact pinout and thermal characteristics defined in the datasheet for your PCB layout.
Selection Notes
Select this component when high-voltage isolation and noise reduction are critical for AC switching applications. The integrated zero-crossing feature distinguishes it from standard photo-triacs by ensuring turn-on only near voltage zero points. Evaluate thermal management requirements based on the SMD-6 package power dissipation limits under continuous operation conditions.
Part Context
This part belongs to Vishay's VO415x series of zero-crossing photo-triac optocouplers. The series is designed for reliable AC power control where electromagnetic compatibility is important. The X007T designation indicates a specific surface-mount packaging option within the broader VO4158 product family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Verify pin compatibility and electrical specifications before considering alternative manufacturers.
