# NSP4201MR6T1G-TP

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

NSP4201MR6T1G-TP 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 | TVS-protected I/O line steered to ground, rated 5V max reverse working voltage, 30A peak pulse (8/20µs) and ±30kV ESD per IEC 61000-4-2. |
| 2 | GND | power_in | Ground reference to which all I/O pins are clamped; the TVS zener anode connects here. |
| 3 | I/O2 | passive | TVS-protected I/O line steered to ground, rated 5V max reverse working voltage, 30A peak pulse (8/20µs) and ±30kV ESD per IEC 61000-4-2. |
| 4 | I/O3 | passive | TVS-protected I/O line steered to ground, rated 5V max reverse working voltage, 30A peak pulse (8/20µs) and ±30kV ESD per IEC 61000-4-2. |
| 5 | VCC | power_in | Supply-rail connection of the TVS array (zener cathode), rated 60A peak pulse (8/20µs) VCC pin to ground. |
| 6 | I/O4 | passive | TVS-protected I/O line steered to ground, rated 5V max reverse working voltage, 30A peak pulse (8/20µs) and ±30kV ESD per IEC 61000-4-2. |
