UMZ27NUM-TP from TECH PUBLIC, in a SOT-323. 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 line 1 (TVS diode anode); 22V reverse working voltage, 25V min breakdown at 1mA, ±15kV air / ±8kV contact ESD per IEC 61000-4-2. |
| 2 | I/O2 | passive | Protected line 2 (TVS diode anode); 22V reverse working voltage, 25V min breakdown at 1mA, ±15kV air / ±8kV contact ESD per IEC 61000-4-2. |
| 3 | COMMON | passive | Common node of the two uni-directional TVS diodes (shared by both lines in the schematic). |
