UBT23A05L02
UMW · ESD And Surge Protection (TVS/ESD) · SOT-23
UBT23A05L02 from UMW, in a SOT-23. 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 | ESD-protected high-speed data line 1 (steering diodes to pin 3), 5V working voltage, 0.8 pF max capacitance to GND per the datasheet table. |
| 2 | I/O2 | passive | ESD-protected high-speed data line 2 (steering diodes to pin 3), 5V working voltage, 0.8 pF max capacitance to GND per the datasheet table. |
| 3 | GND | power_in | Ground reference of the TVS array, common to both I/O pins; I/O-to-GND capacitance is specified at 0V, 1MHz. |
