ESDU5V0K4
UMW · ESD And Surge Protection (TVS/ESD) · SOT-363
ESDU5V0K4 from UMW, in a SOT-363. 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 | bidirectional | ESD-protected bidirectional line whose clamp is referenced to GND, with 0.8 pF maximum junction capacitance per channel (I/O to GND). |
| 2 | GND | power_in | Ground reference for all ESD clamps; per-channel reverse stand-off, breakdown and clamping limits are specified to GND. |
| 3 | I/O3 | bidirectional | ESD-protected bidirectional line whose clamp is referenced to GND, with 0.8 pF maximum junction capacitance per channel (I/O to GND). |
| 4 | I/O4 | bidirectional | ESD-protected bidirectional line whose clamp is referenced to GND, with 0.8 pF maximum junction capacitance per channel (I/O to GND). |
| 5 | VCC | power_in | Supply-side pin with its own ESD clamp; the datasheet gives reverse stand-off of 5 V (VRWM) for VCC to GND. |
| 6 | I/O2 | bidirectional | ESD-protected bidirectional line whose clamp is referenced to GND, with 0.8 pF maximum junction capacitance per channel (I/O to GND). |
