Overview
The Vishay 15CTQ045S is a dual Schottky rectifier in a D2PAK (TO-263) package. It features a common cathode configuration with two independent anodes, providing a total average forward current of 15 A (7.5 A per leg). The device has a maximum repetitive peak reverse voltage of 45 V and operates at junction temperatures up to 150 °C. Key electrical characteristics include a maximum forward voltage drop of 0.51 V at 7.5 A and 125 °C, and a non-repetitive surge current rating of 810 A.
Feature Summary
- Optimized proprietary barrier technology for very low forward voltage drop
- High purity epoxy encapsulation for enhanced mechanical strength and moisture resistance
- Guard ring structure designed for enhanced ruggedness and long-term reliability
- Qualified for automotive Q101 level standards
Applications
- Switching power supplies
- Converters
- Freewheeling diodes
- Reverse battery protection
Procurement Notes
Verify the specific suffix against the ordering information table to confirm packaging orientation and lead-free status. The 'S' indicates the D2PAK case style. Confirm thermal management requirements align with the specified junction-to-case thermal resistance values provided in the datasheet specifications.
Selection Notes
Select this component when a dual common cathode Schottky rectifier is required in a surface-mount D2PAK footprint. Ensure the circuit voltage does not exceed the 45 V maximum rating. Consider the 150 °C operating temperature capability for high-temperature environments where standard silicon rectifiers may be limited.
Part Context
This part belongs to the Vishay 15CTQ series of center tap Schottky rectifiers. The 'S' suffix specifically denotes the D2PAK (TO-263) surface mount package variant, distinct from the '-1' suffix which indicates the TO-262 through-hole package. Both variants share identical electrical ratings and internal die specifications.
Replacement Considerations
Public confirmed substitute part numbers: 15CTQ045-1 (TO-262 package equivalent), 15CTQ045SPBF (Lead-free TO-262 package). Verify pinout compatibility and thermal interface requirements when substituting between D2PAK and TO-262 packages.
