VO4158M-X007T

Overview

The VO4158M-X007T is a single-channel optoisolator from Vishay Semiconductor Opto Division featuring a triac output with an integrated zero-crossing detection circuit. It provides high isolation capability of 5300 Vrms between input and output sections. The device utilizes a surface-mount 6-SMD package for compact integration. Key electrical specifications include a maximum off-state voltage of 800 V, a peak on-state current of 300 mA, and a minimum static dv/dt rating of 5 kV/µs. The trigger current (Ift) is limited to a maximum of 3 mA.

Feature Summary

• Integrated zero-crossing detection circuitry for precise AC load switching
• High isolation voltage rating of 5300 Vrms for safety compliance
• Robust noise immunity with a minimum static dv/dt rating of 5 kV/µs

Applications

• Solid-state relays for AC power control
• Motor control circuits requiring phase-angle firing
• Industrial automation systems with isolated AC switching

Procurement Notes

Verify the specific suffix 'X007T' corresponds to the tape-and-reel packaging configuration required for your assembly line. Confirm that the 6-SMD gull-wing footprint matches your PCB design guidelines. Ensure the 800 V off-state voltage meets the peak line voltage requirements of your target application. Cross-reference the datasheet for any recent product change notifications regarding pinout or material composition updates.

Selection Notes

Select this component when zero-crossing switching is mandatory to minimize electromagnetic interference and inrush currents. The 5300 Vrms isolation makes it suitable for applications requiring reinforced insulation barriers. Consider the 300 mA RMS current limit when sizing for resistive or inductive loads. The surface-mount format is ideal for automated manufacturing processes where space constraints are critical.
