FUXINSEMI
Matches all key specs (200V, 3A, SMB package) and offers improved efficiency with a lower forward voltage.
SS3200B is a 200V, 3A Schottky rectifier in a common DO-214AA (SMB) package, used for high-efficiency rectification. Key alternatives exist with matching or improved performance.
High risk if substituting with a non-Schottky diode. Low risk if using a verified Schottky alternative.
The DO-214AA (SMB) package is standardized, making physical replacement straightforward.
Direct replacement for SS3200B should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Use MBRS3200T3G-FS for a direct-fit replacement or SS10200B for an upgrade in current handling.
The main risk is accidentally using a standard or fast-recovery diode instead of a Schottky, which can cause circuit malfunction or failure.

| Feature / factor | SS3200B | MBRS3200T3G-FS | SS10200B | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | DO-214AA (SMB) | DO-214AA (SMB) | DO-214AA (SMB) | DO-214AA (SMB) — Same package and pin count.; SS10200B: Same package and pin count. | |
| Diode Type | Schottky | Schottky | Schottky | Schottky — Both are Schottky diodes.; SS10200B: Both are Schottky diodes. | |
| Voltage | 200V | 200V | 200V | 200V — Reverse voltage matches.; SS10200B: Reverse voltage matches. | |
| Current | 3A | 3A | 10A | 3A / 10A — Forward current matches.; SS10200B: Significantly higher current rating provides more design margin. | |
| Forward Voltage | 0.95V @ 3A | 0.84V @ 3A | - | 0.84V @ 3A — Lower Vf means higher efficiency. | |
| Surge Current | 80A | - | 250A | 250A — Higher surge capability increases robustness. |
Verified drop-in options for SS3200B 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.
