Overview
The VO4158D-X009T is a zero-crossing photo-triac optocoupler from Vishay, featuring a single channel in a 6-SMD surface-mount package. It provides 5300 Vrms isolation voltage and supports a maximum continuous output current of 300 mA with an off-state voltage (VDRM) of 800 V. The device includes an integrated zero-crossing circuit that triggers at approximately 20 V, ensuring low electromagnetic interference during switching. Key electrical parameters include a forward current of 60 mA, forward voltage of 1.2 V, and power dissipation of 600 mW. Operating temperatures range from -55°C to +100°C.
Feature Summary
- Integrated zero-crossing detection circuit for reduced electromagnetic interference
- High isolation voltage capability for safe mains interfacing
- Surface-mount packaging for automated assembly compatibility
Applications
- Solid-state relay driver circuits
- AC motor speed control systems
- Lighting dimmer applications
Procurement Notes
Verify the specific suffix X009T confirms the 6-SMD gull-wing package variant rather than through-hole DIP versions. Confirm RoHS compliance status as indicated in official datasheets. Ensure design-in reviews match the 800 V off-state voltage rating against load requirements. Cross-reference manufacturer part numbers to distinguish between standard and tape-and-reel packaging options.
Selection Notes
Select this component when zero-crossing switching is required to minimize noise in AC loads. Compare the 300 mA continuous current limit against peak load demands. Evaluate the 5300 Vrms isolation barrier against safety standards. Consider the 6-SMD footprint constraints versus available PCB space. Verify thermal management needs given the 600 mW power dissipation rating.
Part Context
This part belongs to the VO415x series of triac output optocouplers. It shares functional similarities with other Vishay zero-crossing devices but differs in package type and specific electrical ratings. The X009T suffix denotes the surface-mount configuration, distinguishing it from PDIP variants like the VO4158D.
Replacement Considerations
Publicly confirmed substitutes include IL4118-X009T and VO4157M-X009T. Verify pinout compatibility and electrical parameter alignment before substitution.
