DT1042-02SR-7 from Diodes Incorporated, in a SOT-143. 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 | GND | power_in | Ground (VSS) reference pin; the I/O clamp diodes and VCC-to-VSS TVS return to it, with ESD rated to ±16kV contact and ±18kV air per IEC 61000-4-2. |
| 2 | I/O1 | passive | Protected channel 1 I/O line clamped to VSS, with typical 0.65pF capacitance (0.8pF max), 0.5µA max leakage at 5V and ±6A peak pulse current (8/20µs). |
| 3 | I/O2 | passive | Protected channel 2 I/O line clamped to VSS, with typical 0.65pF capacitance (0.8pF max), 0.5µA max leakage at 5V and ±6A peak pulse current (8/20µs). |
| 4 | VCC | power_in | Positive reference rail for the steering diodes, with 5.0V max reverse working voltage and 6.2V min breakdown voltage at 1mA to VSS. |
