RS1KFP

Single Diodes Overview

The RS1KFP is a surface mount fast recovery rectifier manufactured by onsemi, housed in an SOD-123EP package. It features a repetitive peak reverse voltage of 800 V and supports an average forward rectified current of 1.2 A. The device exhibits a maximum instantaneous forward voltage of 1.3 V at rated current and a typical reverse recovery time of 300 ns. Peak forward surge current capacity reaches 50 A for an 8.3 ms half-sine wave pulse. Operating junction temperature ranges from -55 °C to +150 °C.

• Industrial device qualification per AEC-Q101 standards

Single Diodes Applications

• High frequency switching power supplies
• DC-DC converter circuits
• General purpose rectification in industrial electronics

Single Diodes Procurement Notes

Verify the specific ordering suffix matches the required voltage rating and packaging configuration. Confirm that the component meets RoHS compliance and Green Molding Compound requirements for your assembly process. Ensure the tape and reel specifications align with your pick-and-place equipment capabilities before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when high efficiency and low power loss are critical design parameters. The ultra-thin profile makes it suitable for space-constrained applications requiring robust thermal management through the enlarged cathode pad. Consider the 300 ns reverse recovery time for high-frequency operation where switching losses must be minimized.

Single Diodes Part Context

This part belongs to the RS1JFP-RS1MFP series of surface mount fast recovery rectifiers. All variants share identical electrical characteristics regarding current handling and thermal resistance, differing only in their peak reverse voltage ratings. The RS1KFP specifically provides the 800 V blocking capability within this standardized package family.

Single Diodes Replacement Considerations

Direct substitutes include RS1JFP (600V) or RS1MFP (1000V) if voltage margins allow. Verify pinout compatibility and ensure the replacement maintains the SOD-123EP footprint and thermal dissipation characteristics.
