**Diodes Incorporated** · ESD And Surge Protection (TVS/ESD) · SOT-26

DT1042-04SO-7 from Diodes Incorporated, in a SOT-26. 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 | bidirectional | ESD/TVS channel 1 I/O, rated to VSS with ±6 A peak pulse current (IEC 61000-4-5, 8/20 µs) and 5.5 V maximum DC operating voltage. |
| 2 | Vss | power_in | Common ground/reference pin for all four I/O clamps; the datasheet rates the operating voltage at 5.5 V I/O to VSS. |
| 3 | I/O2 | bidirectional | ESD/TVS channel 2 I/O, rated to VSS with ±6 A peak pulse current (IEC 61000-4-5, 8/20 µs) and 5.5 V maximum DC operating voltage. |
| 4 | I/O3 | bidirectional | ESD/TVS channel 3 I/O, rated to VSS with ±6 A peak pulse current (IEC 61000-4-5, 8/20 µs) and 5.5 V maximum DC operating voltage. |
| 5 | Vcc | power_in | Positive supply/clamp reference pin; the datasheet gives a reverse working voltage of 5.0 V (VCC to VSS). |
| 6 | I/O4 | bidirectional | ESD/TVS channel 4 I/O, rated to VSS with ±6 A peak pulse current (IEC 61000-4-5, 8/20 µs) and 5.5 V maximum DC operating voltage. |
