VS-40CTQ045STRRPBF

Diode Arrays Overview

The Vishay VS-40CTQ045STRRPBF is a high-performance Schottky rectifier featuring a center tap configuration with two independent diodes in a common cathode arrangement. Housed in a TO-263AB (D2PAK) surface-mount package, it provides a maximum average forward current of 40 A 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 Apk per leg. It supports reliable operation up to a maximum junction temperature of 150 °C and meets MSL level 1 requirements.

Diode Arrays Procurement Notes

Verify the specific ordering suffix 'TRRPBF' corresponds to the tape and reel packaging variant rather than tube packaging. Confirm that the component meets lead-free specifications as indicated by the PbF designation. Ensure compatibility with standard SMD reflow soldering profiles, noting the LF maximum peak temperature rating of 260 °C and MSL level 1 classification.

Diode Arrays Selection Notes

Select this component when a dual-diode common cathode topology is required for synchronous rectification or freewheeling applications. The D2PAK package offers a balance between thermal dissipation capabilities and board space constraints. Consider the 45 V voltage rating and 40 A current capacity against the specific load requirements of the target circuit design.

Diode Arrays Part Context

This part belongs to the Vishay High Performance Schottky Rectifier series, designed for demanding power-conversion applications. The product line emphasizes low forward voltage drops and high reliability through specialized barrier technologies. The VS-40CTQ045STRRPBF specifically targets surface-mount implementations requiring robust thermal performance and efficient power handling in compact form factors.

Diode Arrays Replacement Considerations

The datasheet lists VS-40CTQ045SPbF and VS-40CTQ045-1PbF as related variations within the same electrical specification family. These alternatives differ primarily in packaging format, such as antistatic plastic tubes versus the tape and reel configuration of the STRRPBF variant.
