TPESDA25-4BP6 from TECH PUBLIC, in a SOT-563. 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 | I/O1 | passive | ESD/TVS protected line 1 (bi-directional), clamps to ground; 25V max reverse working voltage, ±15kV air / ±8kV contact ESD per IEC 61000-4-2. |
| 2 | GND | power_in | Ground reference for the TVS diode array, connected internally to pin 5. |
| 3 | I/O2 | passive | ESD/TVS protected line 2 (bi-directional), clamps to ground; 25V max reverse working voltage, 5pF max junction capacitance. |
| 4 | I/O3 | passive | ESD/TVS protected line 3 (bi-directional), clamps to ground; 25V max reverse working voltage, 60W peak pulse power (8/20µs). |
| 5 | GND | power_in | Ground reference for the TVS diode array, connected internally to pin 2. |
| 6 | I/O4 | passive | ESD/TVS protected line 4 (bi-directional), clamps to ground; 25V max reverse working voltage, 2A peak pulse current (8/20µs). |
