VO4258H-X007T

Overview

The VO4258H-X007T is a single-channel phototriac output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a non-zero-crossing triac output capable of handling an off-state voltage (VDRM) of 800 V and a maximum continuous output current of 300 mA. The device provides high isolation with an insulation voltage of 5300 Vrms. It operates within a temperature range of -55°C to +100°C and is housed in a 6-SMD, gull-wing surface-mount package.

Feature Summary

• High dV/dt capability for reliable triggering in noisy environments
• Low input forward current requirement for efficient drive
• Non-zero-crossing output for phase control applications

Applications

• Solid state relays
• Motor control circuits
• Lighting dimmers

Procurement Notes

Verify the specific suffix X007T confirms the tape-and-reel packaging format required for automated assembly processes. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

Selection Notes

Select this component when non-zero-crossing triac triggering is required for AC power control. Ensure the 800 V blocking voltage meets circuit requirements. Verify that the 6-SMD footprint aligns with the PCB layout constraints.

Part Context

This part belongs to the VO4258H family of phototriac optocouplers. It shares functional characteristics with other Vishay triac outputs but differs in packaging and reel specifications defined by the X007T suffix.

Replacement Considerations

Direct pin-to-pin replacements may include other Vishay VO425x series variants with compatible packaging. Cross-manufacturer substitutes require verification of isolation voltage, trigger current, and package dimensions.
