TPESD7205WTT1G

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-323

TPESD7205WTT1G 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 IO1 passive ESD-protected I/O line 1 (TVS diode to pin 3), 5V max reverse working voltage, 0.5pF typ junction capacitance to pin 3, ±20kV air / ±15kV contact IEC 61000-4-2.
2 IO2 passive ESD-protected I/O line 2 (TVS diode to pin 3), 5V max reverse working voltage, 0.5pF typ junction capacitance to pin 3, 0.35pF typ between pin 1 and pin 2.
3 GND power_in Common cathode/return pin of the two TVS diodes, connected to ground; pins 1 and 2 are clamped relative to it.
