Overview
The Vishay 15CTQ040 is a center-tap Schottky rectifier featuring dual anodes with a common cathode. It provides a maximum average forward current of 15 A and a maximum DC reverse voltage of 40 V. The device operates within a junction temperature range of -55 °C to 150 °C. Key electrical characteristics include a maximum forward voltage drop of 0.70 V at 15 A and 25 °C, and a maximum non-repetitive surge current of 810 A. The component utilizes a TO-220AB package.
Feature Summary
- Optimized for very low forward voltage drop with moderate leakage current
- Reliable operation up to 150 °C junction temperature using proprietary barrier technology
- High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance
- Guard ring design for enhanced ruggedness and long term reliability
Applications
- Switching power supplies
- Converters
- Freewheeling diodes
- Reverse battery protection
Procurement Notes
Verify the specific ordering suffix when purchasing. Standard production units are supplied in tubes containing 50 pieces. Lead-free (PbF) variants exist within this series; confirm the exact part number matches the required environmental compliance specifications for the intended assembly process.
Selection Notes
Select based on the 40 V reverse voltage rating and 15 A continuous current requirement. Ensure thermal management accommodates the 3.50 °C/W junction-to-case thermal resistance per leg. Verify that the application does not exceed the 810 A non-repetitive surge current limit during transient events.
Part Context
This component belongs to the 15CTQ... Series of Schottky rectifiers from Vishay High Power Products. The series includes variants with 35 V, 40 V, and 45 V ratings. All models share the same dual-anode common-cathode configuration and TO-220AB package form factor.
Replacement Considerations
Direct substitutes within the same series include the 15CTQ035 and 15CTQ045. These parts maintain identical current ratings and packaging but differ in their maximum DC reverse voltage specifications.
