UESD3.3DT5G from onsemi, in a SOT-723. 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 | CATHODE | passive | Cathode terminal of the ESD protection diode; the datasheet gives no separate electrical limit for this pin beyond the device maximum ratings (ESD ±30 kV IEC 61000-4-2 contact/air, 16 kV HBM, 400 V MM, 40 A IEC 61000-4-4). |
| 2 | CATHODE | passive | Second cathode terminal of the ESD protection diode, connected internally with pin 1 as stated in the pin assignment; no separate limit is given for this pin. |
| 3 | ANODE | passive | Anode terminal of the ESD protection diode, which clamps ESD transients to the cathode pins; the datasheet gives no separate electrical limit for this pin. |
