RURD620CCS9A-F085P

Overview

The RURD620CCS9A-F085P is an ultrafast dual diode manufactured by onsemi, formerly Fairchild Semiconductor. It features a 200 V reverse voltage rating and a continuous forward current of 6 A per element in a dual configuration. The device utilizes silicon nitride passivated ion-implanted epitaxial planar construction for robust performance. Key electrical characteristics include a maximum reverse leakage current of 100 µA and a soft recovery time of less than 25 ns. It operates within a junction temperature range of -55°C to +175°C and is avalanche energy rated.

Feature Summary

• Ultrafast soft recovery characteristics minimize ringing and electrical noise in switching circuits.
• Low forward voltage drop reduces power loss in switching transistors.
• Silicon nitride passivated ion-implanted epitaxial planar construction ensures durability.
• Avalanche energy rated capability provides resilience against transient voltage events.

Applications

• Freewheeling and clamping diodes in switching power supplies
• Rectifiers in general-purpose power switching applications
• High-frequency DC-DC converter circuits

Procurement Notes

Verify the specific suffix F085P against the official onsemi datasheet to confirm packaging details and tape-and-reel specifications. Ensure the component matches the legacy Fairchild Semiconductor origin if cross-sourcing from onsemi inventory. Confirm RoHS compliance status and lead-free designation as indicated in the manufacturer's documentation prior to procurement.

Selection Notes

Select this component for applications requiring fast recovery times below 25 ns and high thermal stability up to 175°C. The dual configuration suits bridge rectifier or synchronous rectification topologies where space efficiency is critical. Compare the 200 V rating against circuit peak inverse voltage requirements to ensure adequate margin. Consider the TO-252AA package constraints for thermal management in high-current scenarios.

Part Context

This part belongs to the RURD series of ultrafast diodes, originally developed by Fairchild Semiconductor and now managed by onsemi. The series is designed for high-efficiency power conversion, offering superior soft recovery compared to standard fast recovery diodes. The dual diode format integrates two independent elements in a single package, simplifying board layout for full-wave or half-wave rectification applications.

Replacement Considerations

Direct substitutes include the RURD620CCS9A and RURD620CCS9A-F085 from onsemi/Fairchild. Other compatible ultrafast dual diodes with similar 6A/200V ratings should be verified for pinout compatibility and thermal resistance equivalence before substitution.
