ESD5425E

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-23-6

ESD5425E from TECH PUBLIC, in a SOT-23-6. 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 data line 1 (steering-diode pair to the VCC and GND rails), 0.3pF typical I/O-to-I/O and 0.8pF max to ground, 5V reverse working voltage.
2 GND power_in Ground reference pin, at the bottom rail of the schematic and the anode side of the central TVS diode that every I/O pin is rated against.
3 I/O2 passive Protected data line 2 (steering-diode pair to the VCC and GND rails), 0.3pF typical I/O-to-I/O and 0.8pF max to ground, 5V reverse working voltage.
4 I/O3 passive Protected data line 3 (steering-diode pair to the VCC and GND rails), 0.3pF typical I/O-to-I/O and 0.8pF max to ground, 5V reverse working voltage.
5 VCC power_in Power line protected by the central TVS diode (Vcc-GND), with 300W peak pulse power at 8/20µs and 18V max clamping at IPP=17A.
6 I/O4 passive Protected data line 4 (steering-diode pair to the VCC and GND rails), 0.3pF typical I/O-to-I/O and 0.8pF max to ground, 5V reverse working voltage.
