BSD5A181V35

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

BSD5A181V35 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 K passive Cathode of the unidirectional TVS diode, on the cathode-band side of the package and connected to the protected line, with VRWM of 18 V and VBR of 19.8 V (min) at 1 mA.
2 A passive Anode of the unidirectional TVS diode, normally connected to ground, with a clamping voltage of 27 V (max) at IPP = 8 A (8/20 µs).
