BORN · ESD And Surge Protection (TVS/ESD) · SOT-23
BST23A242V 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 | Protected line terminal of the TVS diode; for the BST23A242V (24 V reverse stand-off) the junction capacitance is 20 pF to pin 2 and 30 pF to pin 3 at VR = 0 V, f = 1 MHz. |
| 2 | 2 | passive | Protected line terminal of the TVS diode; for the BST23A242V (24 V reverse stand-off) the junction capacitance is 20 pF to pin 1 and 30 pF to pin 3 at VR = 0 V, f = 1 MHz. |
| 3 | 3 | passive | Common terminal; the datasheet states pin 3 is the cathode for unidirectional devices only, and the junction capacitance is 30 pF to pins 1 and 2 at VR = 0 V, f = 1 MHz for the BST23A242V. |
