15CTQ035STRL

Overview

The Vishay 15CTQ035STRL is a dual common-cathode Schottky rectifier in the TO-262 (D2PAK) surface-mount package. It features a 35 V maximum repetitive reverse voltage and a total average forward current of 15 A, with each leg rated at 7.5 A. The device utilizes proprietary barrier technology to achieve low forward voltage drop and high-frequency operation capabilities. Designed for robust performance, it supports junction temperatures up to 150 °C and includes guard ring protection for enhanced ruggedness.

Feature Summary

• Dual common-cathode configuration optimized for low forward voltage drop
• Guard ring structure provides enhanced ruggedness and long-term reliability
• High purity epoxy encapsulation ensures mechanical strength and moisture resistance
• Qualified for automotive applications under AEC-Q101 standards

Applications

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

Procurement Notes

Verify the specific suffix 'TRL' indicates left-oriented tape and reel packaging for the D2PAK case style. Confirm lead-free status via the PbF designation if required by assembly specifications. Ensure compatibility with RoHS directives and check for any process change notifications that may affect component availability or material composition prior to procurement.

Selection Notes

Select this component for applications requiring surface-mount mounting with high surge current capability. The 810 A non-repetitive surge rating supports transient load conditions. Verify thermal management requirements against the 3.50 °C/W junction-to-case thermal resistance per leg. Ensure the operating environment remains within the -55 °C to 150 °C junction temperature range for reliable operation.

Part Context

This part belongs to the Vishay 15CTQ...S/15CTQ...-1 series of Schottky rectifiers. The 'S' suffix denotes the D2PAK (TO-262) package variant, while '-1' refers to the standard TO-262 package. The series is designed for high-efficiency power conversion applications where low forward voltage and high reliability are critical design parameters.

Replacement Considerations

Direct substitutes include other Vishay parts from the same series with different voltage ratings, such as 15CTQ040STRL or 15CTQ045STRL. Cross-manufacturer replacements must match the 15 A total current, 35 V minimum reverse voltage, and D2PAK footprint. Verify pinout compatibility and thermal characteristics before substitution.

FAQ
