Overview
The 85HQ035 is a high-current Schottky rectifier diode manufactured by Microchip Technology. It features a single silicon element designed for general-purpose applications with an average forward current rating of 75 amperes and a maximum repetitive reverse voltage of 35 volts. The device utilizes a metal DO-203AB (DO-5) package, providing robust thermal performance and mechanical stability. It supports a wide operating temperature range from -65 °C to +175 °C and can withstand a non-repetitive peak forward surge current of up to 1200 amperes.
Feature Summary
- Schottky barrier construction for low forward voltage drop
- High thermal stability in metal DO-203AB housing
- Capable of handling significant surge currents
Applications
- General purpose rectification
- Power supply input stages
- Freewheeling diodes in inductive loads
Procurement Notes
Verify the specific suffix against official Microchip documentation to confirm exact electrical tolerances and packaging variations. Ensure the component meets RoHS compliance requirements if mandated by your project specifications. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when a high-current, low-voltage rectification solution is required. The DO-203AB package offers superior heat dissipation compared to plastic alternatives. Consider the 175 °C junction temperature capability for harsh environments. Verify that the 35 V reverse voltage rating provides sufficient margin for the specific circuit application.
Part Context
This component belongs to the HQ series of high-current Schottky rectifiers produced by Microchip Technology. The series is characterized by its ability to handle substantial forward currents while maintaining low power losses. These devices are engineered for reliability in demanding power conversion applications where efficiency and thermal management are critical design factors.
Replacement Considerations
Consult Microchip's official cross-reference guides for verified substitutes. Ensure any replacement matches the 75 A current rating, 35 V reverse voltage, and DO-203AB package dimensions. Verify that alternative components maintain equivalent thermal characteristics and switching speeds.
