NUP4202W1T2G-JSM

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

NUP4202W1T2G-JSM from JSMSEMI, 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/O1 passive High-speed data line 1 protected by a steering-diode pair, with 0.4 pF max capacitance between I/O pins and 1 pF max to ground (VR = 0 V, f = 1 MHz).
2 GND power_in Ground connection for the steering diodes and the TVS diode; IEC61000-4-2 ESD rating of 20 kV contact and 20 kV air.
3 I/O2 passive High-speed data line 2 protected by a steering-diode pair, with 0.4 pF max capacitance between I/O pins and 1 pF max to ground (VR = 0 V, f = 1 MHz).
4 I/O3 passive High-speed data line 3 protected by a steering-diode pair, with 0.4 pF max capacitance between I/O pins and 1 pF max to ground (VR = 0 V, f = 1 MHz).
5 VCC power_in Supply rail (Vcc) protection pin connected to the top diode rail and the TVS diode, with a reverse working peak voltage of 5 V max.
6 I/O4 passive High-speed data line 4 protected by a steering-diode pair, with 0.4 pF max capacitance between I/O pins and 1 pF max to ground (VR = 0 V, f = 1 MHz).
