TPESD24BC3 from TECH PUBLIC, in a SOT-323. 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 | IO1 | passive | TVS protection channel 1 I/O, steered to GND by the diode pair; reverse working voltage 24V, ESD ±30kV contact/air per IEC 61000-4-2. |
| 2 | IO2 | passive | TVS protection channel 2 I/O, steered to GND by the diode pair; reverse working voltage 24V, ESD ±30kV contact/air per IEC 61000-4-2. |
| 3 | GND | power_in | Common ground reference for both TVS channels. |
