BST23C242V

BORN · TVS · SOT-23

BST23C242V 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 PIN 1 passive Protected line terminal of the SOT-23 TVS, with junction capacitance of 20 pF to pin 2 and 30 pF to pin 3 for the BST23C242V (VR = 0 V, f = 1 MHz).
2 PIN 2 passive Protected line terminal of the SOT-23 TVS, with junction capacitance of 20 pF to pin 1 and 30 pF to pin 3 for the BST23C242V (VR = 0 V, f = 1 MHz).
3 3 passive Cathode of the unidirectional device (stated as unidirectional only), with 30 pF junction capacitance to pins 1 and 2 for the BST23C242V (VR = 0 V, f = 1 MHz).
