ESD0302TL from MDD Microdiode Semiconductor, 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 | I/O1 | passive | ESD-protected high-speed data line 1, with 0.2pF typical I/O-to-I/O capacitance, 3.3V max reverse working voltage to GND and 4.2V min breakdown at 1mA. |
| 2 | I/O2 | passive | ESD-protected high-speed data line 2, with 0.2pF typical I/O-to-I/O capacitance, 3.3V max reverse working voltage to GND and 4.2V min breakdown at 1mA. |
| 3 | GND | power_in | Ground reference, connected to the common TVS diode in the circuit diagram, to which both I/O pins are clamped (VC max 10V at IPP=1A, 8/20µs). |
