Diodes Incorporated · ESD And Surge Protection (TVS/ESD) · SOT-23
DESD5V2S2UT-7 from Diodes Incorporated, 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 | 1 | passive | One of the two protected line terminals of the unidirectional TVS; the datasheet measures device capacitance between pin 1 and pin 3 (Note 7). |
| 2 | 2 | passive | The other protected line terminal of the unidirectional TVS; the datasheet measures device capacitance between pin 2 and pin 3 (Note 7). |
| 3 | 3 | passive | Common terminal shared by the two protected paths, used as the reference for the pin 1 and pin 2 capacitance measurements (Note 7). |
