Leiditech · ESD And Surge Protection (TVS/ESD) · 0402
PESD1442U005 from Leiditech, 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 | Bidirectional ESD protection terminal connected to the protected signal line (or GND); rated voltage 14 V max, 15 kV contact / 25 kV air discharge per IEC 61000-4-2. |
| 2 | 2 | passive | Second terminal of the bidirectional ESD diode, connected to the protected signal line or GND; the device is symmetric, with typical capacitance 0.05 pF at VR = 0 V, 1 MHz. |
