US1M-13-F may fit SMA pads but changes Schottky behavior.
B1100-13-F is a 100V 1A SMA Schottky rectifier. Reviewed options need FAE checks before replacement.
Schottky type not matched
SMA mostly matches
discrete diode
PDF checks pending
Direct replacement for B1100-13-F should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Prefer a 100V or higher 1A SMA Schottky with verified 2-pin polarity.
Non-Schottky candidates can raise loss and switching stress.

| Feature / factor | B1100-13-F | US1M-13-F | BYG20G-E3/TR3 | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SMA | SMA | - | SMA — same case | |
| Pinout | 2 pins | 2 pins | - | missing — pin count absent | |
| Voltage | 100 V | 1000 V | - | 400 V — higher VR | |
| Current | 1.0 A | 1.0 A | - | 1.5 A — higher IF | |
| Application | Schottky | ultrafast rectifier | - | rectifier 75ns — not Schottky evidence |
Verified drop-in options for B1100-13-F are limited in the current batch. Review candidates marked Strong match or Datasheet verified, and validate package, pinout, and electrical limits before committing a BOM change.
