B240A-13-F is a same-package 40V Schottky with higher current rating.
B140-13-F is a 40V 1A SMA Schottky rectifier. Same-package Schottky options exist, but pin polarity and losses need review.
VF, leakage, and derating need checks.
SMA matches, pinout not checked.
Discrete diode has no firmware.
Kept parts are catalog matched.
Direct replacement for B140-13-F should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Review B240A-13-F first; use B340A/B340LA for more current margin if thermal limits pass.
Pin polarity and forward-loss data are not fully verified.
