onsemi · ESD Protection Devices · TSOP-6

SZNSP4201MR6T1G from onsemi, in a TSOP-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/O passive Protected I/O line (uni-directional clamp to GND), VRWM 5.0 V max working voltage, clamps to 8.5 V at IPP = 1 A.
2 VN power_in Negative/ground reference pin of the surge protector; surge current return (Pin 5 to Pin 2 for the 500 W 8/20 µs rating).
3 I/O passive Protected I/O line (uni-directional clamp to GND), VRWM 5.0 V max working voltage, clamps to 8.5 V at IPP = 1 A.
4 I/O passive Protected I/O line (uni-directional clamp to GND), VRWM 5.0 V max working voltage, clamps to 8.5 V at IPP = 1 A.
5 VP passive Positive supply/rail reference pin of the surge protector; surge current is applied Pin 5 to Pin 2 for the 500 W 8/20 µs rating, connected to VCC in the application examples.
6 I/O passive Protected I/O line (uni-directional clamp to GND), VRWM 5.0 V max working voltage, clamps to 8.5 V at IPP = 1 A.
