Find the best replacements for the B360B, a 60V, 3A Schottky diode in an SMB package. This guide reviews pin-compatible alternatives, upgrades, and parametric options to help you source a substitute.

AI replacement insight

Electrical riskhigh

Using a non-Schottky or high-Vf diode will increase power loss and heat.

Package risklow

SMB is a standard package, but confirming dimensions is always wise.

Can it be replaced directly?

Direct replacement for B360B should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

STPS3L60U for a direct match, or SS1060B for a current upgrade.

Main risk

Substituting with a non-Schottky diode or one with a higher forward voltage (Vf), leading to lower efficiency and potential overheating.
