GSOT15C-E3-08
UMW · ESD And Surge Protection (TVS/ESD) · SOT-23
GSOT15C-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 | L1 / pin 1 | passive | Connects to signal or data line L1 in BiAs mode, where the protection diodes to pin 3 hold a maximum reverse working voltage of 15 V (VRWM) and a peak pulse current of 8 A (IPPM, 8/20 µs) for GSOT15C; in BiSy mode it is the line pin. |
| 2 | L2 / pin 2 | passive | Connects to signal or data line L2 in BiAs mode, with the same GSOT15C limits of 15 V VRWM and 8 A IPPM (8/20 µs) to pin 3; in BiSy mode it is tied to ground (or swapped with pin 1). |
| 3 | GND / pin 3 | power_in | Ground reference pin that must be connected to ground in BiAs mode, and must not be connected in BiSy mode (single-line use with pin 1 to the line and pin 2 to ground). |
