VOM3052T

Overview

The VOM3052T is a Triac output optocoupler from Vishay Semiconductor Opto Division, housed in a 4-SOP (2.54mm) package. It features a non-zero crossing output with a peak repetitive off-state voltage of 600V and an isolation voltage of 3750Vrms. The device supports a maximum DC forward current of 60mA and a peak trigger current of 10mA. It exhibits a minimum static dV/dt rating of 1.5kV/µs and operates within a temperature range of -40°C to 100°C.

Feature Summary

• Non-zero crossing triac output for immediate load control
• High static dV/dt immunity of 1.5kV/µs
• Compact 4-SOP surface mount packaging

Applications

• Solid state relays
• Motor control circuits
• Lighting control systems

Procurement Notes

Verify the specific suffix 'T' confirms the tape and reel packaging format. Confirm the 4-SOP package variant matches the design footprint requirements. Ensure the non-zero crossing characteristic aligns with the application's switching needs rather than zero-crossing alternatives.

Selection Notes

Select this component when immediate turn-on is required without waiting for the AC line zero crossing. The 4-SOP package suits space-constrained designs. Verify that the 600V blocking voltage meets the load requirements and that the 10mA trigger current is compatible with the driving logic level.

Part Context

This part belongs to the VOM305x series of Vishay optocouplers. It shares functional similarities with other non-zero crossing triac outputs but differs in package type and specific electrical ratings compared to variants like the VO3052. The 4-SOP form factor distinguishes it from DIP or larger SMD options in the same family.

Replacement Considerations

Check for direct pin-compatible substitutes within the Vishay VOM305x series. Verify equivalent dV/dt ratings and isolation voltages when considering cross-manufacturer replacements.
