BSD5C051U from BORN, in a SOD-523. 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 terminal of the bidirectional silicon-avalanche ESD protection diode on the protected data/power line, with the device rated at 5.0 V reverse stand-off (VRWM), 6.0 V minimum to 8.5 V typical reverse breakdown at 1 mA, and 20 V typical clamping at 3 A (8/20 µs). |
| 2 | 2 | passive | The other terminal of the bidirectional silicon-avalanche ESD protection diode on the protected data/power line, rated for 60 W peak pulse power (tp = 8/20 µs) and IEC 61000-4-2 ±15 kV contact / ±20 kV air. |
