MSKSEMI · ESD And Surge Protection (TVS/ESD) · 0402
PESD0402MS09-MS from MSKSEMI, in a 0402. 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 | 1 | passive | One terminal of the bi-directional single-line ESD protection diode, connected to the protected signal line; rated for 9 V continuous operating voltage (VDC) and 8 kV contact / 15 kV air IEC 61000-4-2 discharge. |
| 2 | 2 | passive | Second terminal of the bi-directional single-line ESD protection diode, interchangeable with the other terminal and connected to ground or the return side; rated for 9 V continuous operating voltage (VDC). |
