S3BB
onsemi · Schottky Diodes · DO-214AA
S3BB from onsemi, in a DO-214AA. 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 of the S3BB rectifier, identified on the package by the color band, rated for a 100 V repetitive peak reverse voltage and 3 A average forward rectified current. |
| 2 | Anode | passive | Anode terminal of the S3BB rectifier, opposite the cathode color band, carrying forward current up to 3 A average with an 80 A peak non-repetitive surge (8.3 ms half sine). |
