TPNUP2105LT1G

TECH PUBLIC · ESD Protection Devices · SOT-23

TPNUP2105LT1G 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/O 1 passive Protected line 1 of the bi-directional TVS pair, connected through the back-to-back diodes to pin 3, with 25pF typical junction capacitance between pin 1 and pin 2.
2 I/O 2 passive Protected line 2 of the bi-directional TVS pair, connected through the back-to-back diodes to pin 3, with reverse working voltage of 24V max.
3 Common passive Common node joining both TVS diode branches (pin 1 and pin 2 each connect to it), with ESD rating of ±30kV air and contact per IEC 61000-4-2.
