VOM3052

Overview

The VOM3052 is a phototriac optoisolator featuring a Gallium Arsenide infrared LED optically coupled to a non-zero crossing triac. It provides 3750Vrms isolation voltage and supports a peak repetitive off-state voltage of 600V. The device operates with a maximum DC forward current of 60mA and an RMS on-state current of 70mA. It maintains a minimum static dV/dt of 1.5kV/µs and functions within a temperature range of -40°C to 100°C.

Feature Summary

• Non-zero crossing triac output for flexible phase control applications
• High isolation voltage capability of 3750Vrms
• Robust noise immunity with high static dV/dt rating

Applications

• Solid state relays
• Motor control circuits
• Lighting dimmer switches

Procurement Notes

Verify the specific suffix (e.g., X001T) to confirm package type, as standard VOM3052 typically denotes SOP-4. Confirm isolation ratings and certification marks against the official datasheet for your region. Ensure thermal management meets the specified operating temperature range during integration.

Selection Notes

Select this component when non-zero crossing switching is required for AC load control. Compare the 70mA RMS current limit against load requirements. Verify that the 3750Vrms isolation meets system safety standards. Consider the SOP-4 package dimensions for PCB layout constraints.

Part Context

Part of the VOM305x series from Vishay Semiconductor Opto Division. Designed for general-purpose AC power switching where precise zero-crossing timing is not critical. Offers a compact surface-mount solution compared to traditional DIP optocouplers.

Replacement Considerations

Check pinout compatibility with existing designs. Verify equivalent isolation voltage and current ratings in potential substitutes. Ensure the replacement also features non-zero crossing behavior if phase control is used.
