PSOT12C

TECH PUBLIC · ESD Protection Devices · SOT-23

PSOT12C 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 (TVS diode anode); clamps to pin 3, 12V max reverse working voltage, 450W peak pulse power (8/20µs).
2 I/O2 passive Protected line 2 (TVS diode anode); clamps to pin 3, 12V max reverse working voltage, 450W peak pulse power (8/20µs).
3 COMMON passive Common cathode of the two TVS diodes (ground/reference side in uni-directional use); pin 1 or pin 2 to pin 3 capacitance is 100pF max at VR=0, 1MHz.
