SS810 8A 100V Schottky Barrier Rectifier | SMD Replacement Diode for Iceriver Crypto Miner Control Board Repair
The SS810 is an 8A / 100V Schottky barrier rectifier in SMD form, widely used on Iceriver crypto miner control boards. Surface-mount package with low forward voltage drop and fast switching, ideal for the protection and rectification roles it plays on the control-board input stage and on auxiliary rails feeding the network and management circuits.
Drop-in replacement when the original part fails — typical failure modes include thermal stress from sustained miner duty, reverse-voltage transients during PSU events, and physical damage during cable handling. A dead SS810 usually shows as a control board that won't boot or that loses one of its rails. Swap the part, verify continuity, and the board returns to normal operation.
When to Replace the SS810
- Iceriver control board won't boot after a power event — protection diode failed short, blocking the input rail.
- Auxiliary rail dead or noisy on the control board — rectifier degraded, output capacitor not charging cleanly.
- Visible burn or discoloration on the SS810 package — thermal or surge damage, replace immediately.
- Reverse leakage measured outside spec — degraded junction, replace before downstream damage to the rail.
- Preventive control board refurbishment — Schottkys drift over years of thermal cycling, refresh alongside electrolytics.

FAQ — SS810 Schottky Rectifier
Q: Is the SS810 interchangeable with SS810D, SS810L, or other Schottky variants?
A: Same 8A / 100V envelope across the SS810 family, with minor case-style differences (D = DO-214AB / SMC, L = SOD-128). Verify the footprint on your Iceriver board before substituting between variants — the electrical performance is interchangeable but the pad layout differs.
Q: How do I identify a failed SS810 on the board?
A: Forward-bias diode test with a multimeter — a healthy SS810 reads ~0.3-0.5V forward and infinite reverse. Short in either direction or open in both = failed. Visual inspection catches the obvious burn cases.
Q: Can I substitute a higher-current Schottky if I'm out of stock?
A: A higher-current Schottky in the same package generally works as a substitute (more current headroom is fine), but verify the package footprint matches and that the part fits within the board's thermal envelope. Don't substitute lower-rated parts.
Q: Bulk pricing for repair shops?
