TPESDA25-4BP6

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-563

TPESDA25-4BP6 from TECH PUBLIC, in a SOT-563. 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 ESD/TVS protected line 1 (bi-directional), clamps to ground; 25V max reverse working voltage, ±15kV air / ±8kV contact ESD per IEC 61000-4-2.
2 GND power_in Ground reference for the TVS diode array, connected internally to pin 5.
3 I/O2 passive ESD/TVS protected line 2 (bi-directional), clamps to ground; 25V max reverse working voltage, 5pF max junction capacitance.
4 I/O3 passive ESD/TVS protected line 3 (bi-directional), clamps to ground; 25V max reverse working voltage, 60W peak pulse power (8/20µs).
5 GND power_in Ground reference for the TVS diode array, connected internally to pin 2.
6 I/O4 passive ESD/TVS protected line 4 (bi-directional), clamps to ground; 25V max reverse working voltage, 2A peak pulse current (8/20µs).
