AI replacement insight

Electrical risklow

Low for SBR3A40SA-13. Medium for parts with higher Vf, requiring thermal analysis.

Package risklow

All top candidates use the same SMA package, ensuring physical compatibility.

Sourcing risklow

All recommended alternatives are from the same manufacturer, Diodes Incorporated.

Can it be replaced directly?

Yes, SBR3A40SA-13 is a strong candidate for replacement, sharing the same package, current, and forward voltage, with an improved voltage rating.

Best replacement path

SBR3A40SA-13 offers an easy upgrade path with a higher voltage margin and matching key parameters.

Main risk

The primary risk when substituting is an increased forward voltage (Vf), which can reduce efficiency and increase heat. Some alternatives have a Vf up to 40% higher.
