MDD
An upgrade with higher voltage and current ratings in the same package.
SS26B is a 2A, 60V Schottky rectifier in a DO-214AA (SMB) package, commonly used for high-efficiency power conversion. Several alternatives with matching or improved ratings are available.
Low if replacing with another Schottky diode of equal or greater voltage/current ratings.
Low for candidates in the same DO-214AA (SMB) package.
This is a common diode type with multiple manufacturers, suggesting good availability.
SS310B is a strong replacement offering higher voltage (100V) and current (3A). SS36B is also a good option with higher current (3A) at the same voltage.
Upgrade to a higher voltage and current part like SS310B for increased robustness and design margin.
The primary risk is substituting with a non-Schottky diode (e.g., standard or fast recovery), which would increase power loss and could cause circuit failure.

| Feature / factor | SS26B | SS310B | SS2200B | SS36B | Compatibility / risk |
|---|---|---|---|---|---|
| Package | DO-214AA (SMB) | DO-214AA (SMB) | DO-214AA (SMB) | DO-214AA (SMB) | DO-214AA (SMB) — Same package ensures form-fit compatibility.; SS2200B: Same package ensures form-fit compatibility.; SS36B: Same package ensures form-fit compatibility. |
| Voltage | 60.0V | 100.0V | 200.0V | 60.0V | 100.0V / 200.0V / 60.0V — Higher voltage rating provides increased design margin.; SS2200B: Significantly higher voltage rating provides superior design margin.; SS36B: Voltage rating matches target; no extra margin. |
| Current | 2.0A | 3.0A | 2.0A | 3.0A | 3.0A / 2.0A — Higher current rating provides more capacity.; SS2200B: Current rating matches the target.; SS36B: Higher current rating provides more capacity. |
| Diode Type | Schottky | Schottky | Schottky | Schottky (inferred) | Schottky / Schottky (inferred) — Functionally equivalent Schottky diode.; SS2200B: Functionally equivalent Schottky diode.; SS36B: Rule engine flagged for verification, but datasheets indicate Schottky type. |
SS310B is an excellent alternative, offering higher voltage (100V) and current (3A) in the same SMB package, which provides greater design margin.
