Littelfuse · ESD And Surge Protection (TVS/ESD) · 0402
PESD0402-240 from Littelfuse, 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 ESD protector, rated 24 VDC continuous maximum operating voltage with 0.25 pF typical capacitance; connect to the protected signal line, with the opposite terminal to ground. |
| 2 | 2 | passive | Second terminal of the bi-directional ESD protector, interchangeable with the other terminal because the part has no polarity mark; 10 µA maximum leakage at 24 VDC. |
