Single Diodes datasheet and documents for S85QR
Single Diodes Overview
The S85QR is a silicon standard recovery rectifier from the GeneSiC Semiconductor S85 series, housed in a DO-5 (DO-203AB) stud mount package. It features a repetitive peak reverse voltage of 1200 V and a continuous forward current rating of 85 A at Tj = 25 °C. The device exhibits a maximum forward voltage of 1.1 V and supports a surge non-repetitive forward current of 1000 A. Operating temperatures range from -55 °C to +150 °C, with a thermal resistance junction-to-case of 9 °C/W.
Single Diodes Feature Summary
- High surge capability for handling transient current loads
- Not ESD sensitive for simplified handling
- Standard polarity configuration with cathode stud
Single Diodes Applications
- Industrial power conversion systems
- General purpose rectification circuits
- Power supply input stages
Single Diodes Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm datasheet revision dates and specific ordering suffixes match requirements. Check for end-of-life status as indicated by some sources. Ensure proper mounting torque specifications are followed during installation to maintain thermal performance and mechanical integrity.
Single Diodes Selection Notes
Select this component for applications requiring robust standard recovery characteristics with high current capacity. The DO-5 package facilitates efficient heat dissipation via stud mounting. Consider the 1200 V blocking voltage for medium-voltage AC-DC conversion tasks. Evaluate thermal management needs against the specified junction-to-case resistance.
Single Diodes Part Context
Part of the S85 family of silicon standard recovery diodes, offering various voltage ratings from 800 V to 1200 V. Manufactured by GeneSiC Semiconductor, these devices are designed for general-purpose rectification. The S85QR specifically denotes the 1200 V variant within this standardized product line.
Single Diodes Replacement Considerations
S85K, S85M, S85Q variants share identical packages and current ratings but differ in reverse voltage ratings. Verify voltage requirements before substitution. Reverse polarity versions (e.g., S85QR-R) exist with anode studs.
