VT6045CBP-M3/4W

Diode Arrays Overview

The VT6045CBP-M3/4W is a dual common cathode Trench MOS Barrier Schottky (TMBS) rectifier manufactured by Vishay General Semiconductor. It features a TO-220AB package with a maximum repetitive peak reverse voltage of 45 V and an average forward rectified current of 60 A per device (30 A per diode). The component exhibits a low forward voltage drop, reaching 0.33 V at 10 A and 15 A when the junction temperature is 125 °C. It supports a peak forward surge current of 320 A and operates within a junction temperature range up to 200 °C in DC bypass mode applications.

Diode Arrays Feature Summary

• Utilizes Trench MOS Schottky technology to achieve ultra-low forward voltage and reduced power losses.
• Designed for high-efficiency operation with a maximum junction temperature of 200 °C in solar bypass mode.
• Compliant with RoHS standards and halogen-free, meeting JESD 201 class 1A whisker test requirements.

Diode Arrays Applications

• Solar cell junction box bypass protection
• Photovoltaic panel bypass diodes
• DC forward current circuits without reverse bias

Diode Arrays Procurement Notes

Verify the specific ordering suffix to confirm the package type, as the base model includes variants such as the TO-262AA configuration. Confirm compliance with RoHS directives and halogen-free status through official documentation. Ensure that thermal management aligns with the specified operating temperatures for both AC and DC modes. Validate application suitability against manufacturer disclaimers regarding life-saving or critical systems.

Diode Arrays Selection Notes

Select this component for photovoltaic applications requiring robust bypass protection with minimal conduction losses. The TMBS technology offers superior performance compared to standard Schottky diodes. Consider the thermal resistance characteristics when designing heatsinking solutions. Verify that the 45 V rating matches the system's maximum reverse voltage requirements under all operating conditions.

Diode Arrays Part Context

This part belongs to Vishay's TMBS rectifier family, specifically engineered for solar energy applications. It integrates two independent diodes in a single common cathode configuration. The M3 suffix indicates lead-free construction and environmental compliance. The device is optimized for use in harsh outdoor environments typical of solar installations.

Diode Arrays Replacement Considerations

Direct replacements include the VIT6045CBP-M3/4W variant, which utilizes the TO-262AA package instead of the TO-220AB form factor. Both share identical electrical specifications and functionality. Ensure mechanical fitment compatibility before substituting between these package types.

Diode Arrays FAQ
