D3V3F4U6S-7

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

D3V3F4U6S-7 from Diodes Incorporated, 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 CH1 passive ESD-protected channel 1 input for high-speed data lines, with 0.85pF typical channel capacitance.
2 VN power_in Negative (ground) reference pin of the TVS array; leakage and capacitance are measured from the other pins to pin 2.
3 CH2 passive ESD-protected channel 2 input for high-speed data lines, with 0.85pF typical channel capacitance.
4 CH3 passive ESD-protected channel 3 input for high-speed data lines, with 0.85pF typical channel capacitance.
5 VP passive Positive reference pin of the TVS array, connected to the internal TVS diode, with a reverse working voltage of 3.3V maximum.
6 CH4 passive ESD-protected channel 4 input for high-speed data lines, with 0.85pF typical channel capacitance.
