KUU · ESD And Surge Protection (TVS/ESD) · SOT-363

KLC0504F from KUU, in a SOT-363. 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 bidirectional Data line I/O protected by the TVS, rated for reverse working voltage 5.0 V to GND with 0.45-0.50 pF I/O-to-GND capacitance and 10 V clamping at 1 A (8/20 µs).
2 GND power_in Ground reference for all protection paths, with 0.45-0.50 pF I/O-to-GND and 0.80 pF Vcc-to-GND capacitance specified against this pin.
3 I/O bidirectional Data line I/O protected by the TVS, rated for reverse working voltage 5.0 V to GND with 0.20 pF typical I/O-to-I/O capacitance and 15 V clamping at 4 A (8/20 µs).
4 I/O bidirectional Data line I/O protected by the TVS, rated for reverse working voltage 5.0 V to GND with 0.20 pF typical I/O-to-I/O capacitance and 15 V clamping at 4 A (8/20 µs).
5 VCC power_in Vcc supply pin protected by the TVS, with 0.80 pF Vcc-to-GND capacitance and 15 V clamping at 8 A (8/20 µs).
