1N457 from onsemi, in a DO-35. 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 colour-band end of the DO-35 body; the diode blocks up to 70 V maximum repetitive reverse voltage (VRRM). |
| 2 | A | passive | Anode, the lead opposite the colour band; average rectified forward current is 200 mA maximum and VF is 1.0 V max at IF = 20 mA for the 1N457. |
