ESD5425E from TECH PUBLIC, in a SOT-23-6. 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 | Protected data line 1 (steering-diode pair to the VCC and GND rails), 0.3pF typical I/O-to-I/O and 0.8pF max to ground, 5V reverse working voltage. |
| 2 | GND | power_in | Ground reference pin, at the bottom rail of the schematic and the anode side of the central TVS diode that every I/O pin is rated against. |
| 3 | I/O2 | passive | Protected data line 2 (steering-diode pair to the VCC and GND rails), 0.3pF typical I/O-to-I/O and 0.8pF max to ground, 5V reverse working voltage. |
| 4 | I/O3 | passive | Protected data line 3 (steering-diode pair to the VCC and GND rails), 0.3pF typical I/O-to-I/O and 0.8pF max to ground, 5V reverse working voltage. |
| 5 | VCC | power_in | Power line protected by the central TVS diode (Vcc-GND), with 300W peak pulse power at 8/20µs and 18V max clamping at IPP=17A. |
| 6 | I/O4 | passive | Protected data line 4 (steering-diode pair to the VCC and GND rails), 0.3pF typical I/O-to-I/O and 0.8pF max to ground, 5V reverse working voltage. |
