SR2150 from MDD（Microdiode Electronics）, in a DO-15. 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 color band on the DO-15 molded plastic body; SR2150 blocks up to 150 V DC (VRRM 150 V) and carries 2.0 A average forward current. |
| 2 | A | passive | Anode terminal at the end of the body opposite the color band; solder plated axial lead, 0.70-0.86 mm (0.028-0.034 in) diameter, 25.4 mm minimum length. |
