S2MB from hongjiacheng, 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 terminal, the end marked by the cathode line; the part blocks up to 1000 V (VRRM/VDC) for S2MB and carries 2.0 A average forward current. |
| 2 | A | passive | Anode terminal, opposite the cathode line; forward voltage is 1.0 V maximum at IF=2.0A. |
