BSD3C031L2

BORN · ESD And Surge Protection (TVS/ESD) · SOD-323

BSD3C031L2 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 Terminal 1 of the bidirectional ESD protection diode that protects one data/power line, rated for IEC 61000-4-2 ±30 kV contact and ±30 kV air discharge with a 3.3 V reverse stand-off voltage (datasheet gives these as device-level ratings, not per-pin).
2 2 passive Terminal 2 of the bidirectional ESD protection diode that protects one data/power line, rated for IEC 61000-4-2 ±30 kV contact and ±30 kV air discharge with a 3.3 V reverse stand-off voltage (datasheet gives these as device-level ratings, not per-pin).
