VS-40CTQ045-1-M3

Diode Arrays Overview

The Vishay VS-40CTQ045-1-M3 is a high-performance Schottky rectifier featuring a center tap configuration with two anodes and a common cathode. It provides a maximum average forward current of 20 A per leg (40 A total) and a repetitive peak reverse voltage of 45 V. The device utilizes proprietary barrier technology to achieve a very low forward voltage drop of 0.48 V at 20 A and 125 °C, while maintaining moderate leakage current. Designed for reliable operation up to a maximum junction temperature of 150 °C, it offers high frequency operation capabilities.

Diode Arrays Procurement Notes

Verify the specific package style required for your design, as this part number corresponds to the TO-262AA outline. Confirm that the 45 V rating and 20 A per leg current capacity align with your circuit's peak and continuous requirements. Ensure thermal management solutions accommodate the specified thermal resistance values for optimal performance under load conditions.

Diode Arrays Selection Notes

Select this component when a center tap topology is necessary for synchronous rectification or full-wave conversion applications. The low forward voltage drop makes it suitable for low-voltage, high-current outputs where minimizing conduction losses is critical. Verify that the operating environment does not exceed the 150 °C maximum junction temperature limit during peak load scenarios.

Diode Arrays Part Context

This device belongs to Vishay's Schottky 'Q' series, designed for high-efficiency rectification. It shares electrical characteristics with the VS-40CTQ045S-M3 but differs in physical packaging. The TO-262AA form factor allows for surface mount or through-hole integration depending on board layout constraints, providing flexibility in assembly processes compared to standard leaded packages.
