1N5406 from LGE, 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, marked by the color band on the molded plastic case; the pin that sees positive voltage when the diode is reverse biased (VRRM 600 V for 1N5406). |
| 2 | A | passive | Anode, the end opposite the color band; conducts forward current up to 3.0 A average (I(AV) at TA = 75 °C) with VF of 1.0 V maximum at 3.0 A. |
