BSD5C051U

BORN · ESD And Surge Protection (TVS/ESD) · SOD-523

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.

  • Symbol: BSD5C051U
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: bsd5c051u-etched.step / bsd5c051u-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bsd5c051u.step / bsd5c051u.glb are the bare package body.
