BST23C122V

BORN · ESD And Surge Protection (TVS/ESD) · SOT-23

BST23C122V from BORN, in a SOT-23. 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 bidirectional Protected line of the bidirectional ESD diode array, rated for a 12 V reverse stand-off (VRWM) and a 350 W peak pulse power (tp = 8/20 µs); junction capacitance from Pin 1 to Pin 3 is 30 to 35 pF at VR = 0 V, f = 1 MHz.
2 2 bidirectional Protected line of the bidirectional ESD diode array, rated for a 12 V reverse stand-off (VRWM) and a 350 W peak pulse power (tp = 8/20 µs); junction capacitance from Pin 2 to Pin 3 is 30 to 35 pF at VR = 0 V, f = 1 MHz.
3 3 passive Common reference pin of the ESD diode array; the datasheet measures junction capacitance from Pins 1 and 2 to this pin, and does not name it as ground.
