VS-12TQ040PBF

Single Diodes Overview

The VS-12TQ040PBF is a high-performance Schottky rectifier manufactured by Vishay Semiconductors. It features a single die configuration housed in a D2PAK (TO-262) package with lead-free construction. The device supports a maximum average forward current of 15 A and offers a maximum DC reverse voltage rating of 40 V. Key electrical characteristics include a typical forward voltage drop of 0.50 V at 15 A and 125 °C, and a maximum non-repetitive surge current of 990 A. It operates reliably up to a junction temperature of 150 °C.

Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm package type and packaging format. The 'S' suffix indicates the D2PAK package, while 'PbF' denotes lead-free compliance. Confirm that the required thermal management solution aligns with the specified junction-to-case thermal resistance values provided in the datasheet.

Single Diodes Selection Notes

Select this component when low forward voltage drop is critical for efficiency in high-frequency applications. Ensure the circuit design accommodates the 40 V reverse voltage rating and the 15 A average forward current capability. Consider the thermal performance requirements, as the device is rated for operation up to 150 °C junction temperature.

Single Diodes Part Context

This part belongs to the VS-12TQ...SPbF series of high-performance Schottky rectifiers from Vishay Semiconductors. The series includes variants with different reverse voltage ratings, specifically 35 V, 40 V, and 45 V. All members share the same 15 A current rating and D2PAK package form factor.

Single Diodes Replacement Considerations

Direct substitutes within the same series include the VS-12TQ035PBF (35 V rating) and VS-12TQ045PBF (45 V rating). These parts share identical current ratings, package dimensions, and thermal characteristics, differing only in their maximum reverse voltage specifications.
