A form-fit-function alternate with a higher current rating (10A), but requires review of reverse leakage current.
SS810 is an 8A, 100V Schottky rectifier in an SMC package, used for high-efficiency rectification. When seeking alternatives, it is critical to match the low forward voltage and fast switching characteristics of a Schottky diode.
Key parameters like forward voltage (Vf) and reverse leakage (Ir) differ, requiring engineering review.
Candidates share the same standard SMC package, ensuring physical compatibility.
No drop-in replacement is confirmed without datasheet review. SS10100 and SK1010C are form-fit-function matches in the same SMC package but have parametric differences.
SS10100 offers an increased current rating but requires datasheet verification of its reverse leakage current.
Using a non-Schottky diode (e.g., standard or fast recovery) will likely cause circuit failure due to higher forward voltage and slower switching speed.

| Feature / factor | SS810 | SS10100 | SK1010C | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SMC (DO-214AB) | SMC (DO-214AB) | SMC (DO-214AB) | SMC (DO-214AB) — Same package ensures physical compatibility.; SK1010C: Same package ensures physical compatibility. | |
| Voltage | 100V | 100V | 100V | 100V — Voltage rating is identical; no increased safety margin.; SK1010C: Voltage rating is identical. | |
| Current | 8A | 10A | 10A | 10A — Higher current rating provides more operational margin.; SK1010C: Higher current rating provides more operational margin. | |
| Forward Voltage | 0.85V @ 8A | 0.85V @ 10A | 0.95V @ 10A | 0.85V @ 10A / 0.95V @ 10A — Similar Vf, but at a higher current.; SK1010C: Higher Vf will increase power dissipation and heat. | |
| Reverse Leakage | 1mA | 100uA to 10mA | 0.5mA @ 100V | 100uA to 10mA / 0.5mA @ 100V — Conflicting data found; worst-case is much higher than target. Datasheet verification is required.; SK1010C: Lower reverse leakage is an improvement. |
SS10100 is a strong candidate, offering a higher current rating (10A) in the same package. However, its reverse leakage current must be verified from the datasheet to ensure it meets your circuit's requirements.
