VO4154D-X007T

Triac, SCR Output Optoisolators Overview

The VO4154D-X007T is a single-channel zero-crossing photo Triac optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor input and a PhotoTriac output, housed in a 6-SMD (PDIP-6 Gull Wing) surface-mount package. The device provides 5300 Vrms isolation voltage and supports a maximum continuous output current of 300 mA with a blocking voltage of 400 V. Key electrical parameters include a forward current of 60 mA, a forward voltage of 1.2 V, and a peak trigger current of 1.6 mA. It operates within a temperature range of -55°C to +100°C.

Triac, SCR Output Optoisolators Feature Summary

• Integrates a dedicated zero-crossing detection circuit to minimize electromagnetic interference during AC switching operations.
• Utilizes a PhotoTriac output stage capable of handling high continuous currents for direct AC load control.
• Provides robust galvanic isolation between input and output circuits via a 5300 Vrms dielectric barrier.

Triac, SCR Output Optoisolators Applications

• Solid-state relays requiring precise AC phase control
• Motor speed controllers for AC induction motors
• Industrial heating element regulation systems

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix X007T corresponds to the reel packaging configuration required for your assembly line. Confirm that the 6-SMD gull-wing footprint matches your PCB design guidelines. Ensure the 400V blocking voltage rating meets the peak line voltage requirements of your target application circuit before finalizing procurement.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is mandatory to reduce electrical noise in AC power applications. The 400V output rating suits standard low-voltage AC systems. Compare against the VO4156D variant if higher voltage blocking capabilities are needed. Ensure the 1.6mA trigger current aligns with your microcontroller or driver GPIO capabilities.

Triac, SCR Output Optoisolators Part Context

This part belongs to the VO415x series of Vishay's zero-crossing Triac output optocouplers. It shares architectural similarities with other members like the VO4156D but differs in output voltage ratings. The series is designed for industrial AC switching applications where low EMI generation is critical.

Triac, SCR Output Optoisolators Replacement Considerations

The VO4156D-X007T is a verified substitute offering identical functionality with a higher 600V blocking voltage rating. Verify pinout compatibility and thermal management requirements when swapping between these variants.
