Overview
The Vishay 19TQ015STRR is a Schottky rectifier in the D2PAK package. It features a maximum average forward current of 19 A and a maximum repetitive peak reverse voltage of 15 V. The device supports junction temperatures up to 125 °C and offers an ultra-low forward voltage drop, typically 0.32 V at 19 A and 75 °C. It includes a guard ring for enhanced ruggedness and is designed for high-frequency operation.
Feature Summary
- Optimized for OR-ing applications with ultra-low forward voltage drop
- Guard ring structure provides enhanced ruggedness and long-term reliability
- High purity, high temperature epoxy encapsulation ensures mechanical strength and moisture resistance
Applications
- Parallel switching power supplies
- Reverse battery protection
- Redundant power subsystems
Procurement Notes
Verify the ordering suffix 'TRR' corresponds to tape and reel right orientation as specified in the datasheet. Confirm Pb-free status if required by the application. Ensure thermal management aligns with the 1.50 °C/W junction-to-case thermal resistance rating for reliable operation within the specified temperature range.
Selection Notes
Select this component for designs requiring low forward voltage drop to minimize power loss in parallel configurations. Verify that the 15 V reverse voltage rating meets the circuit requirements. Consider the D2PAK package dimensions and mounting torque specifications during PCB layout and assembly planning.
Part Context
This part belongs to the 19TQ015S Schottky rectifier series from Vishay High Power Products. It utilizes proprietary barrier technology for reliable operation at elevated junction temperatures. The product is designed and qualified for automotive Q101 level standards, ensuring suitability for demanding environments.
Replacement Considerations
Substitutes include variants with different packaging or orientation suffixes such as 19TQ015STRL (left oriented) or 19TQ015STRPBF (lead-free). Verify pinout compatibility and thermal characteristics when replacing with other manufacturers' parts.
