SR5150 from MDD（Microdiode Electronics）, in a DO-201AD. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode terminal marked by the polarity symbol on the body; for SR5150 it blocks up to 150 V repetitive peak reverse (VRRM) and conducts 5.0 A average forward current. |
| 2 | A | passive | Anode terminal at the opposite axial lead from the polarity marking; carries the 5.0 A average forward current of the SR5150 (150 A peak surge, 8.3 ms). |
