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). |
