TWGMC
A strong pin-compatible alternative with matching key electrical parameters and package.
Find the best replacements for the FUXINSEMI SS36FA, a 60V 3A Schottky diode. This guide provides pin-compatible alternatives and functional upgrades, with detailed engineering analysis.
Check forward voltage (Vf) to ensure thermal performance is not degraded.
Verify SOD-123 vs SOD-123FL dimensions for your layout.
Multiple manufacturers offer parts with the same name but slight spec variations.
Yes, DSK36 and DSS36 are considered direct replacements for SS36FA, sharing the same package, voltage, and current ratings.
Use DSK36 or DSS36 for a near drop-in replacement, after verifying the forward voltage and package from the datasheet of your specific source.
The primary risk is sourcing a variant with higher forward voltage (Vf) or a slightly different package (SOD-123FL), impacting thermals and layout.

| Feature / factor | SS36FA | DSK36 | DSS36 | DSK320 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SOD-123 | SOD-123 / SOD-123FL | SOD-123 / SOD-123FL | SOD-123 | SOD-123 / SOD-123FL — FUXINSEMI version is SOD-123 match; others may be SOD-123FL.; DSS36: FUXINSEMI version is SOD-123 match; others may be SOD-123FL.; DSK320: Package matches. |
| Voltage | 60V | 60V | 60V | 200V | 60V / 200V — Voltage rating matches.; DSS36: Voltage rating matches.; DSK320: Higher voltage rating provides more margin. |
| Current | 3.0A | 3.0A | 3.0A | 3.0A | 3.0A — Current rating matches.; DSS36: Current rating matches.; DSK320: Current rating matches. |
| Vf | 0.70V @ 3A | ~0.70V @ 3A | 0.7V @ 3A | ~0.92V @ 3A | ~0.70V @ 3A / 0.7V @ 3A / ~0.92V @ 3A — Forward voltage is a close match.; DSS36: Forward voltage is a close match.; DSK320: Higher Vf increases power loss. |
| Ir | 0.1mA | 0.5mA | - | - | 0.5mA — Reverse leakage is higher but likely acceptable. |
DSK36 and DSS36 from manufacturers like FUXINSEMI are strong pin-compatible candidates with nearly identical electrical specifications. Always verify the specific datasheet.
