Single Diodes Procurement Notes

Verify the specific package variant (e.g., Axial, TO-220AC, DPAK) required for your design, as the base part number covers multiple mechanical styles. Confirm RoHS compliance status and check for any discontinuation notices associated with specific suffixes or ordering codes before finalizing procurement plans.

Single Diodes Selection Notes

Select this component for circuits requiring fast recovery characteristics in discontinuous conduction mode. Ensure thermal management aligns with the specified junction-to-case resistance values. Verify that the 520 V rating provides adequate margin for the specific DC blocking voltage present in the target application circuit.

Single Diodes Part Context

This device belongs to the MUR series of ultrafast rectifiers manufactured by onsemi. It is engineered specifically for power factor correction and general-purpose switching applications where rapid recovery and low conduction losses are critical performance factors.

Single Diodes Replacement Considerations

Consult the datasheet's ordering information table for direct equivalents such as MUR550APFG, MURD550PFG, MUR550PFG, or MURF550PFG depending on the required package style.
