ESDU5V0H4-MS from MSKSEMI, in a SOT-23-6. 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 | IO1 | bidirectional | Connect to I/O; the ESD protection clamps this unidirectional line for a 5V working voltage. |
| 2 | GND | power_in | Connect to GND, the reference for the ESD clamping paths. |
| 3 | IO2 | bidirectional | Connect to I/O; the ESD protection clamps this unidirectional line for a 5V working voltage. |
| 4 | IO3 | bidirectional | Connect to I/O; the ESD protection clamps this unidirectional line for a 5V working voltage. |
| 5 | Vcc | power_in | Connect to Vcc; the reverse stand-off (working) voltage is 5V. |
| 6 | IO4 | bidirectional | Connect to I/O; the ESD protection clamps this unidirectional line for a 5V working voltage. |
