ES3A from BORN, in a SMB. 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 SMB molded plastic case; ES3A blocks up to 50 V repetitive peak reverse voltage. |
| 2 | A | passive | Anode terminal of the fast recovery rectifier diode, rated 3.0 A maximum average forward rectified current. |
