VT2045C-M3/4W

Diode Arrays Overview

The VT2045C-M3/4W is a dual low-voltage Trench MOS Barrier Schottky (TMBS) rectifier manufactured by Vishay General Semiconductor. It features a common cathode configuration in TO-220AB and TO-262AA packages. The device provides a maximum repetitive peak reverse voltage of 45 V and a total average forward rectified current of 20 A, with 10 A per diode. Peak forward surge current reaches 160 A per diode. Forward voltage drop is specified at 0.41 V at 10 A and 0.33 V at 5 A. Operating junction temperature ranges from -40 °C to +150 °C.

Diode Arrays Procurement Notes

Verify the specific package variant required, as the base model covers both TO-220AB and TO-262AA configurations. Confirm compliance requirements against the latest Vishay material categorization definitions. Ensure thermal management aligns with the specified junction temperature limits and derating curves provided in the official datasheet documentation.

Diode Arrays Selection Notes

Select this component for applications requiring low forward voltage characteristics and high efficiency in switching environments. The TMBS technology offers superior performance compared to standard Schottky rectifiers. Verify that the 45 V reverse voltage rating accommodates circuit transients and that the 20 A total current capacity meets load requirements without exceeding thermal resistance limits.

Diode Arrays Part Context

This part belongs to the VT2045C/VIT2045C family of dual low-voltage Trench MOS Barrier Schottky Rectifiers. The M3 suffix indicates halogen-free, RoHS-compliant terminals with matte tin plating. The /4W designation specifies tube delivery packaging for the TO-220AB and TO-262AA cases. These devices are designed for general-purpose rectification in power electronics.

Diode Arrays Replacement Considerations

Direct substitutes include the VT2045C-M3 for the TO-220AB package and the VIT2045C-M3 for the TO-262AA package. Verify pinout compatibility and thermal resistance specifications when replacing components in existing designs.
