SET23A15L02 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 | I/O1 | passive | TVS I/O line 1 (cathode of the first diode), protected against ESD, EFT and lightning surges; working voltage 15V (VRWM), 1µA max leakage at VR=15V. |
| 2 | I/O2 | passive | TVS I/O line 2 (cathode of the second diode), protected against ESD, EFT and lightning surges; working voltage 15V (VRWM), 1µA max leakage at VR=15V. |
| 3 | GND | power_in | Common anode/ground reference for both TVS diodes; for bidirectional protection of one line, use pins 1 and 2 as the line and pin 3 as the common. |
