S3KB from onsemi, in a DO-214AA(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 | Cathode | passive | Cathode terminal, identified by the polarity mark on the package; the S3KB is rated for a repetitive peak reverse voltage VRRM of 800 V and an average forward rectified current IF(AV) of 3 A. |
| 2 | Anode | passive | Anode terminal; the S3KB withstands a peak forward surge current IFSM of 80 A (8.3 ms single half sine-wave superimposed on rated load). |
