Overview
The 75HQ035 is a single-element silicon Schottky rectifier diode manufactured by Microchip Technology. It features an 80 A maximum average forward current and a 40 V repetitive peak reverse voltage rating. The device utilizes a DO-203AB (DO-5) stud mount package with the cathode connected to the case. It operates within a junction temperature range of -65 °C to 175 °C and supports a non-repetitive peak forward surge current of 1200 A.
Feature Summary
- Schottky barrier construction for low forward voltage drop
- Stud mount design for efficient thermal dissipation
- High surge current capability for robust operation
Applications
- General purpose rectification
- Power supply circuits
- Industrial power conversion
Procurement Notes
Verify the specific datasheet version from Microchip Technology to confirm exact electrical limits and mechanical dimensions. Ensure the procurement channel provides authentic components with traceable documentation. Cross-reference the ordering part number against official manufacturer lists to avoid counterfeit or obsolete stock. Confirm RoHS compliance status if required for your assembly process.
Selection Notes
Select this component when high current handling and fast switching characteristics are required in a ruggedized package. The stud mount configuration necessitates appropriate heatsinking infrastructure. Evaluate the thermal resistance requirements against the expected ambient operating conditions to ensure reliable performance under load.
Part Context
This device belongs to the Microchip Technology discrete semiconductor portfolio, specifically within the power Schottky diode category. It is designed for applications requiring high reliability and efficiency in power management systems. The DO-203AB package is a standard form factor for high-current industrial and automotive electronics.
Replacement Considerations
Consult official substitution guides for compatible alternatives. Verify that any replacement matches the 80 A current rating, 40 V voltage rating, and DO-203AB mounting style. Electrical parameters such as forward voltage and reverse leakage must be compared against the original specifications.
