VO4158D-X007T

Overview

The VO4158D-X007T is a Vishay Semiconductor Opto Division single-channel optocoupler featuring a photo-triac output. It utilizes a surface-mount 6-SMD (PDIP-6 Gull Wing) package. Key electrical parameters include an isolation voltage of 5300 Vrms, a maximum forward current of 60 mA, and a peak repetitive off-state voltage of 600 V. The device incorporates a zero-crossing detection circuit to minimize electromagnetic interference during switching. It supports a maximum continuous output current of 300 mA and operates within a temperature range of -55°C to +100°C.

Feature Summary

• Integrated zero-crossing detection circuit for low-noise AC power control
• High isolation voltage rating of 5300 Vrms for robust safety barriers
• Photo-triac output capable of handling significant load currents
• Surface-mount packaging designed for automated assembly processes

Applications

• Solid-state relays for industrial automation
• AC motor speed control circuits
• Lighting dimmer applications
• General-purpose AC load switching

Procurement Notes

Verify the specific suffix X007T corresponds to the required tape and reel packaging configuration. Confirm that the 600V blocking voltage meets the peak line voltage requirements of the target application. Ensure the zero-crossing feature aligns with the noise sensitivity constraints of the design. Check for any recent product change notifications regarding manufacturing site transfers or material updates.

Selection Notes

Select this component when high-voltage isolation and low electromagnetic interference are critical. The integrated zero-crossing circuit distinguishes it from non-zero-crossing variants like the VO4256D. Consider the 600V rating against potential voltage spikes in the AC line. Evaluate the thermal performance within the 6-SMD footprint if operating near the upper temperature limits.

Part Context

This part belongs to the VO415x series of Vishay's triac output optocouplers. It shares the same physical package and basic isolation characteristics as other members of the family but is specifically configured with internal zero-crossing logic. This differentiates it from standard photo-triac outputs used in phase-control applications where precise timing is required over noise immunity.
