UMW · ESD And Surge Protection (TVS/ESD) · SOT-23
SET23A12L02-E18 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 | Protected I/O line 1 (diode cathode in the pinning schematic) with 12V reverse stand-off voltage, 13.3V minimum breakdown at 1mA and 100pF maximum capacitance to GND. |
| 2 | I/O2 | passive | Protected I/O line 2 (diode cathode in the pinning schematic) with 12V reverse stand-off voltage, 13.3V minimum breakdown at 1mA and 100pF maximum capacitance to GND. |
| 3 | GND | power_in | Common ground pin shared by both TVS diodes (anode side in the pinning schematic), the reference for the I/O pins' clamping. |
