ESDBL18VD3N

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

ESDBL18VD3N 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 the two terminals of the bidirectional ESD protection diode, with a reverse stand-off voltage (VRWM) of 18.0 V and a maximum peak pulse current of 5.5 A at 8/20 µs. Which terminal is pin 1 is shown only in the graphic pin configuration, which is not readable in the extracted text.
2 2 passive The second terminal of the bidirectional ESD protection diode, with a reverse stand-off voltage (VRWM) of 18.0 V and a maximum peak pulse current of 5.5 A at 8/20 µs. Which terminal is pin 2 is shown only in the graphic pin configuration, which is not readable in the extracted text.
