ESDA6V8UW 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 | passive | Protected I/O line connected to the midpoint of a steering diode pair (to pin 5 and GND pin 2), with 0.70pF typ. capacitance to GND. |
| 2 | GND | power_in | Ground, common anode of the lower steering diodes and the TVS diode. |
| 3 | I/O2 | passive | Protected I/O line connected to the midpoint of a steering diode pair, with 0.70pF typ. capacitance to GND and 0.35pF typ. between I/Os. |
| 4 | I/O3 | passive | Protected I/O line connected to the midpoint of a steering diode pair, with 0.70pF typ. capacitance to GND and 0.35pF typ. between I/Os. |
| 5 | VCC | power_in | Positive rail connecting the upper steering diodes and the TVS diode cathode; reverse stand-off voltage 5V max. |
| 6 | I/O4 | passive | Protected I/O line connected to the midpoint of a steering diode pair, with 0.70pF typ. capacitance to GND and 0.35pF typ. between I/Os. |
