MUR550APF

Single Diodes Overview

The MUR550APF is a single ultra-fast recovery rectifier manufactured by onsemi, designed for high-efficiency power conversion applications. It features a 520 V reverse voltage rating and supports a continuous forward current of 5 A. The device utilizes a DCM (Diode Common Cathode) package configuration within the DO-201AD-2 axial leaded form factor. Key electrical characteristics include a maximum forward voltage of 1.15 V at rated current and a typical reverse recovery time of 95 ns. It withstands a surge current of up to 75 A and operates reliably across a junction temperature range from -65 °C to +175 °C.

Single Diodes Procurement Notes

Verify the specific suffix against the official datasheet to confirm exact packaging and tape/reel specifications. Ensure the component meets required RoHS and REACH compliance standards for your region. Confirm that the DO-201AD-2 package dimensions align with your PCB footprint requirements before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when circuit designs require fast switching speeds to reduce electromagnetic interference and power loss. The 520 V rating provides sufficient margin for standard industrial voltage levels. Consider the 5 A current capacity and thermal management needs of the DO-201AD-2 package for proper heat dissipation in the target application environment.

Single Diodes Part Context

This part belongs to the MUR series of ultra-fast recovery rectifiers from onsemi. The series is engineered for general-purpose high-speed switching applications where low reverse recovery charge is critical. The MUR550 variant specifically targets medium-power applications requiring reliable performance under high-frequency operation conditions.

Single Diodes Replacement Considerations

Consult official cross-reference guides for verified substitutes. Ensure any replacement maintains equivalent reverse voltage, forward current, and recovery time specifications.
