Is there a pin-compatible replacement for MBR0580S1-7?

While several candidates like 1N4148W-7-F share the SOD123 package and are pin-compatible, they are not electrically equivalent. They are standard switching diodes, not Schottky diodes, and have different current or voltage ratings.

What risks should I check before replacing MBR0580S1-7?

Before replacing, verify the substitute's diode type (Schottky vs. switching), voltage rating (must be ≥ 80V), current rating (must be ≥ 0.5A), and forward voltage (Vf). Using a part with higher Vf will increase heat and power loss.

MBR0580S1-7 Alternatives, Datasheet & Cross Reference | Diodes Incorporated

MBR0580S1-7 is an 80V, 0.5A Schottky rectifier in a SOD123 package, valued for its low forward voltage. Finding a suitable replacement requires matching these key electrical parameters, as common switching diodes in the same package are not direct substitutes.

AI replacement insight

Electrical riskhigh

Candidates have lower voltage/current ratings or different diode technology (switching vs. Schottky).

Package risklow

All reviewed candidates share the same SOD123 package, making them physically compatible.

Can it be replaced directly?

No direct drop-in replacement was found among the candidates. All options present significant electrical downgrades or functional mismatches requiring engineering review.

Best replacement path

Search for a Schottky diode in a SOD123 package with voltage ≥ 80V and current ≥ 0.5A. Prioritize parts with a forward voltage (Vf) at or below 0.8V.

Main risk

The primary risk is using a non-Schottky diode, which leads to higher forward voltage and increased power dissipation, or selecting a part with insufficient voltage or current ratings.

Recommended alternatives

A switching diode with higher voltage but a lower current rating, requiring careful load analysis.
