Single Diodes datasheet and documents for MR854RLG
Single Diodes Overview
The MR854RLG is a single fast recovery rectifier manufactured by onsemi, designed for through-hole mounting in the DO-201AD package. It features a 400V repetitive peak reverse voltage and a 3A average forward current rating. The device exhibits a typical forward voltage of 1.04V at rated current and a maximum reverse leakage current of 10µA. Its fast recovery time is specified at 150ns, supporting high-efficiency switching applications. The component withstands a non-repetitive peak surge current of 100A and operates within a junction temperature range of -65°C to +125°C.
Single Diodes Feature Summary
- Fast recovery characteristics with 150ns switching time for efficient power conversion
- Glass passivated die construction ensuring reliable operation under thermal stress
- High surge current capability suitable for handling transient load conditions
Single Diodes Applications
- High-frequency switching power supplies
- Free-wheeling diodes in inductive load circuits
- DC-DC converter output rectification
Single Diodes Procurement Notes
Verify the specific suffix RLG against official datasheets to confirm packaging details such as reel or cut tape configuration. Confirm RoHS compliance status directly from manufacturer documentation, as legacy variants may differ. Ensure the procurement channel provides valid traceability for this discontinued or limited-stock component type.
Single Diodes Selection Notes
Select this component when a 400V blocking voltage and 3A continuous current are required in a through-hole form factor. The 150ns recovery time distinguishes it from slower general-purpose rectifiers. Compare forward voltage drop specifications against alternative packages to ensure thermal management compatibility within the target circuit design constraints.
Single Diodes Part Context
This part belongs to the MR854 series of fast recovery rectifiers from onsemi. It shares core electrical parameters with the standard MR854 but differs in packaging format. The series is engineered for general-purpose high-speed rectification in industrial and consumer electronics applications requiring robust performance.
Single Diodes Replacement Considerations
The MR854 serves as a direct functional substitute with identical electrical ratings. Verify that the replacement variant matches the required packaging style for automated assembly processes.
