BSD3C051V from BORN, in a SOD-323. 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 | 1 | passive | One of two bidirectional ESD protection terminals, rated for 5.0 V reverse stand-off (VRWM), 6.0 V minimum breakdown at 1 mA, and 20 V clamping at 16 A (8/20 µs). |
| 2 | 2 | passive | The other bidirectional ESD protection terminal, rated for 5.0 V reverse stand-off (VRWM), 6.0 V minimum breakdown at 1 mA, and 20 V clamping at 16 A (8/20 µs). |
