95HQ015

Overview

The Vishay General Semiconductor - Diodes Division 95HQ015 is a Schottky rectifier optimized for ultra-low forward voltage drop, specifically designed for the OR-ing of parallel power supplies. It features proprietary barrier technology allowing reliable operation up to a 100°C junction temperature. The device has a maximum DC reverse voltage of 15 V and an average forward current rating of 95 A at a case temperature of 44°C with a rectangular waveform. Peak surge current capability reaches 7500 A for a 5 µs sine pulse. The component utilizes a hermetic TO-203AB (DO-5) package.

Feature Summary

• Optimized for OR-ing applications in parallel switching power supplies
• Hermetic package construction for enhanced ruggedness
• Guard ring design for improved long-term reliability
• High frequency operation capabilities

Applications

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

Procurement Notes

Verify that the specific procurement channel provides original manufacturer documentation or traceable certificates of conformity. Confirm the physical integrity of the hermetic DO-5 package upon receipt. Ensure storage conditions align with the specified temperature range to maintain seal integrity. Cross-reference ordering suffixes against official datasheets to confirm exact electrical characteristics before integration into final designs.

Selection Notes

Select this component when low forward voltage drop is critical for efficiency in parallel power supply configurations. The 15 V reverse voltage rating limits suitability to low-voltage systems. Consider the 100°C maximum junction temperature constraint for thermal management. The hermetic package requires specific mounting torque specifications between 23 and 46 Kg-cm to ensure mechanical stability without damaging the seal.

Part Context

This component belongs to the 95HQ series of high-current Schottky rectifiers manufactured by Vishay General Semiconductor - Diodes Division. The series is engineered for industrial-level performance, emphasizing robustness and reliability in demanding power electronics environments. The 95HQ015 variant specifically targets applications requiring high surge current handling alongside minimal conduction losses.

Replacement Considerations

Consult official manufacturer substitution guides for verified equivalents. Generic replacements may not match the hermetic sealing or specific forward voltage characteristics required for OR-ing applications.
