19TQ015STRL

Overview

The Vishay 19TQ015STRL is a Schottky rectifier in the D2PAK package, rated for 15 V reverse voltage and 19 A average forward current. It features an ultra-low forward voltage drop of 0.32 V at 75 °C junction temperature and supports operation up to 125 °C. The device includes a guard ring for enhanced ruggedness and is designed for high-frequency applications with low leakage current.

Feature Summary

• Optimized for OR-ing applications with ultra-low forward voltage drop
• Guard ring structure for enhanced ruggedness and long-term reliability
• High purity epoxy encapsulation for mechanical strength and moisture resistance

Applications

• Parallel switching power supplies
• Reverse battery protection circuits
• Redundant power subsystems

Procurement Notes

Verify that the ordering suffix 'TRL' corresponds to tape and reel packaging with left orientation as specified in the datasheet. Confirm lead-free (PbF) status if required by assembly specifications. Ensure compatibility with D2PAK mounting torque limits between 6 and 12 kgf·cm during installation procedures.

Selection Notes

Select this component when low forward voltage drop is critical for efficiency in parallel power supply configurations. The 15 V rating suits low-voltage DC-DC converters. Verify thermal management requirements against the 1.50 °C/W junction-to-case thermal resistance for continuous operation at 19 A.

Part Context

This part belongs to the 19TQ Schottky series from Vishay High Power Products. It utilizes proprietary barrier technology to achieve reliable performance at elevated temperatures. The TRL suffix indicates specific tape and reel packaging orientation distinct from standard tube or right-oriented reel variants.

Replacement Considerations

Cross-reference with other 19A 15V Schottky diodes in D2PAK packages. Verify pinout compatibility and thermal characteristics before substitution.
