VS-20CTQ045SPBF

Diode Arrays Overview

The VS-20CTQ045SPBF is a dual Schottky rectifier with a common cathode configuration, rated for a maximum DC reverse voltage of 45 V and an average forward current of 2 x 10 A. It utilizes proprietary barrier technology to ensure low reverse leakage at high temperatures, supporting junction operation up to 175 °C. The device features a D2PAK (TO-263AB) surface-mount package with a base common cathode connection. Key electrical characteristics include a typical forward voltage drop of 0.57 V per leg at 10 A and 125 °C, and a maximum non-repetitive surge current of 1060 A.

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel orientation. The 'S' suffix indicates the D2PAK package, while '-1' denotes the TO-262 variant. Confirm RoHS compliance status and halogen-free certification requirements prior to procurement. Ensure thermal management solutions align with the specified thermal resistance values for the selected mounting configuration.

Diode Arrays Selection Notes

Select this component when high-frequency operation and low forward voltage drop are required in space-constrained designs. The 175 °C junction temperature rating allows for higher ambient operating conditions compared to standard 150 °C devices. Consider the D2PAK package for surface-mount assembly where thermal dissipation through the exposed pad is critical. Evaluate the 45 V reverse voltage rating against peak circuit voltages to ensure adequate safety margins.

Diode Arrays Part Context

This part belongs to the VS-20CTQ...SPbF series of dual Schottky rectifiers manufactured by Vishay High Power Products. The series offers various voltage ratings including 35 V and 40 V options within the same package footprint. The product line is designed for high-power applications requiring robust performance and efficiency. The specific model integrates two independent diodes sharing a common cathode terminal.

Diode Arrays Replacement Considerations

Direct substitutes within the same series include VS-20CTQ035SPBF and VS-20CTQ040SPBF for lower voltage requirements. For alternative packages, the VS-20CTQ045-1PbF provides the same electrical specifications in a TO-262 leaded package. Verify pinout compatibility and thermal characteristics before substituting.
