VOM3053T

Overview

The VOM3053T is a single-channel phototriac output optoisolator manufactured by Vishay Semiconductor Opto Division. It features a non-zero crossing triac output capable of handling a peak voltage of 600 V and an RMS on-state current of 70 mA. The device provides high isolation with a rated voltage of 3750 Vrms and offers a minimum static dV/dt of 1.5 kV/µs. It operates within a temperature range of -40°C to 100°C and is housed in a compact 4-SOP surface-mount package.

Feature Summary

• Non-zero crossing triac output for immediate load control
• High isolation voltage rating of 3750 Vrms
• Robust noise immunity with 1.5 kV/µs static dV/dt
• Surface-mount 4-SOP packaging for automated assembly

Applications

• Solid-state relay (SSR) driver circuits
• AC motor speed control systems
• General-purpose AC load switching

Procurement Notes

Verify the specific suffix against official Vishay documentation, as variations such as X001 may indicate different packaging or certification statuses. Confirm active status and lead times directly with authorized distributors. Ensure the selected variant matches the required isolation and thermal specifications for the target application environment.

Selection Notes

Select this component when non-zero crossing operation is required for fast response applications. The 70 mA RMS current rating suits low-to-medium power AC loads. Verify that the 600 V blocking voltage exceeds the peak line voltage. The 4-SOP package is suitable for space-constrained PCB designs requiring surface-mount technology.

Part Context

This part belongs to the VOM305x series of Vishay's Triac and SCR Output Optoisolators. The series is designed for general-purpose AC switching applications where electrical isolation between control and load sides is critical. The VOM3053T specifically denotes the non-zero crossing variant within this family.

Replacement Considerations

Check for direct pin-compatible substitutes within the same Vishay series, such as other VOM305x variants, ensuring identical output type and isolation ratings. Cross-reference with equivalent parts from other manufacturers only if electrical parameters match exactly.
