MSKSEMI · ESD And Surge Protection (TVS/ESD) · 0402
MS0402ESDA-24 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 | A | passive | One end termination (Ag/Ni/Sn) of the non-polar ESD suppressor, rated 5.0 V max continuous DC (VDC) with 250 V maximum clamping voltage at 1 A 8/20µs. |
| 2 | B | passive | Opposite end termination of the non-polar ESD suppressor, interchangeable with the other terminal, typical capacitance 1.0 pF. |
