TPSL05T1G from TECH PUBLIC, 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 line terminal on the anode side of the steering diode and avalanche TVS diode in the pin 1 to pin 2 path, rated for 5V working voltage (VDRM) and 150 W peak pulse power (8/20μs). |
| 2 | 2 | passive | Second diode terminal at the opposite end of the steering diode and TVS diode string from pin 1, with 5V working voltage and 150 W peak pulse power (8/20μs) for the array. |
| 3 | N.C. | unconnected | No internal connection, marked (N.C.) in the pin configuration diagram. |
