1N5825 from SUNMATE Elec, in a DO-27. 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, the lead at the banded end of the DO-201AD body (polarity marked by cathode band); blocks DC voltage up to 40V for the 1N5825 (VRRM/VRWM/VR 20/30/40V across the family) and carries 5.0A average rectified current. |
| 2 | A | passive | Anode, the lead opposite the cathode band; carries up to 5.0A average forward current with a maximum forward voltage of 0.55V at IF = 5.0A. |
