VS-15CTQ040PBF

Diode Arrays Overview

The VS-15CTQ040PBF is a dual Schottky rectifier in a TO-220AB package with a common cathode configuration. It features a maximum repetitive peak reverse voltage of 40 V and a total average forward current rating of 15 A (7.5 A per leg). The device exhibits a typical forward voltage drop of 0.51 V at 7.5 A and 125 °C, with a maximum non-repetitive surge current of 810 A. Operating junction temperatures range from -55 °C to 150 °C.

Diode Arrays Feature Summary

• Optimized proprietary barrier technology for low forward voltage drop and high frequency operation
• High purity, high temperature epoxy encapsulation providing enhanced mechanical strength and moisture resistance
• Guard ring structure designed to enhance ruggedness and ensure long-term reliability

Diode Arrays Applications

• Switching power supplies
• DC-DC converters
• Freewheeling diodes
• Reverse battery protection circuits

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm compliance requirements. The PbF designation indicates lead-free and RoHS compliance, while the -N3 suffix adds halogen-free status. Confirm that the TO-220AB package dimensions and mounting torque specifications align with the target assembly process before finalizing procurement.

Diode Arrays Selection Notes

Select this component when a common cathode dual Schottky rectifier is required for moderate voltage applications up to 40 V. Ensure the thermal management design accommodates the specified junction-to-case thermal resistance of 3.50 °C/W per leg. Verify that the circuit can handle the 810 A non-repetitive surge current capability without exceeding the absolute maximum ratings during transient events.

Diode Arrays Part Context

This part belongs to the VS-15CTQ... series of center tap Schottky rectifiers manufactured by Vishay Semiconductors. The series includes variants with different voltage ratings, specifically 35 V, 40 V, and 45 V options. All members share the same physical package, current handling capabilities, and general electrical characteristics defined by the proprietary barrier technology.

Diode Arrays Replacement Considerations

Direct substitutes within the same series include the VS-15CTQ035PBF (35 V rating) and the VS-15CTQ045PBF (45 V rating). These parts maintain identical pinouts, current ratings, and package dimensions, allowing for potential interchangeability if the voltage margin in the application permits.
