BST23A052V 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 | passive | One of the two protected line terminals of the TVS diode (one bidirectional line or two unidirectional lines), with 100 pF typical junction capacitance to pin 2 at 0 V, 1 MHz for the BST23A052V (5 V working voltage, 300 W peak pulse power at 8/20 µs). |
| 2 | 2 | passive | The second protected line terminal of the TVS diode, with 100 pF typical junction capacitance to pin 1 at 0 V, 1 MHz and 150 pF typical from pin 2 to pin 3 for the BST23A052V. |
| 3 | 3 | passive | Common terminal of the device; the datasheet states it is the cathode for unidirectional operation only, and it is the reference for the 150 pF pin-to-pin-3 junction capacitance on the BST23A052V. |
