TPE12U20AS3

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.
