TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-23
TPE12U20AS3 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 | I/O1 | passive | Protected line 1 (uni-directional TVS diode anode to pin 3), operating voltage 12V (VRWM max 12V), breakdown voltage min 13.5V at IT=1mA. |
| 2 | I/O2 | passive | Protected line 2 (uni-directional TVS diode anode to pin 3), operating voltage 12V (VRWM max 12V), clamping voltage max 19V at IPP=1A (8x20µs). |
| 3 | GND | power_in | Common pin shared by both TVS diodes, connected to ground for two uni-directional lines, with ESD rating ±15kV air and ±8kV contact per IEC 61000-4-2. |
