Overview
The VO4258M-X007T is a single-channel photoTriac optocoupler manufactured by Vishay Semiconductor Opto Division. It features a non-zero-crossing output designed for AC power switching applications. The device provides high isolation with an insulation voltage of 5300 Vrms and supports a maximum repetitive peak off-state voltage (VDRM) of 800 V. It operates within a temperature range of -55°C to +100°C and utilizes a 6-SMD gull-wing package.
Feature Summary
- Non-zero-crossing photoTriac output enables precise phase control for AC loads
- High isolation voltage rating ensures safety in high-voltage circuits
- Robust static dV/dt immunity minimizes false triggering during rapid voltage changes
Applications
- Solid-state relays for AC load switching
- Motor speed control circuits
- Lighting dimmer applications
Procurement Notes
Verify the specific suffix 'X007T' corresponds to the tape and reel packaging configuration required for your assembly process. Confirm that the non-zero-crossing characteristic aligns with your phase-control requirements, as zero-crossing variants exist within the same family. Ensure compatibility with your PCB footprint for the 6-SMD gull-wing package.
Selection Notes
Select this component when phase-angle control is necessary rather than soft-switching at zero voltage crossings. The 800 V blocking capability suits standard mains voltage applications. Consider the 3 mA trigger current requirement for driving LED input design. Verify thermal management needs given the operating temperature range up to 100°C.
Part Context
This part belongs to the VO4258 series of Vishay's Triac output optocouplers. It is distinct from the VO4257 series which typically offers zero-crossing detection. The M suffix indicates the specific package variant. It serves as a solid-state switch interface between low-voltage control logic and high-voltage AC power stages.
Replacement Considerations
Direct substitutes include other non-zero-crossing Triac optocouplers with similar 800 V ratings and 6-SMD packages. Check datasheets for matching trigger current and isolation voltage specifications before substitution.
