GSOT03C-E3-08 from UMW, 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 | 1 | passive | Protected signal/data line L1 in BiAs mode, clamped to pin 3 with a maximum reverse working voltage VRWM of 3.3 V for GSOT03C and rated for ESD immunity of ±30 kV contact and air discharge per IEC 61000-4-2. |
| 2 | 2 | passive | Second protected signal/data line L2 in BiAs mode, clamped to pin 3 with VRWM of 3.3 V for GSOT03C; in BiSy single-line mode it is tied to ground instead, and in that mode the pin 1 to pin 2 path has VRWM of 3.8 V. |
| 3 | 3 | power_in | Ground reference pin connected to system ground in BiAs two-line mode, with the protection diodes from pins 1 and 2 returning to it; it must be left unconnected in BiSy single-line mode. |
