B140-13-F is a 40V 1A SMA Schottky rectifier. Same-package Schottky options exist, but pin polarity and losses need review.

AI replacement insight

Electrical riskmedium

VF, leakage, and derating need checks.

Package riskmedium

SMA matches, pinout not checked.

Firmware risklow

Discrete diode has no firmware.

Sourcing risklow

Kept parts are catalog matched.

Can it be replaced directly?

Direct replacement for B140-13-F should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Review B240A-13-F first; use B340A/B340LA for more current margin if thermal limits pass.

Main risk

Pin polarity and forward-loss data are not fully verified.
