UMW · ESD And Surge Protection (TVS/ESD) · SOT-23
PDT5301-T73 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 | 1 | passive | Protected line terminal of the first bidirectional TVS diode, whose other side connects to common pin 3; rated stand-off voltage 12 V. |
| 2 | 2 | passive | Protected line terminal of the second bidirectional TVS diode, whose other side connects to common pin 3; rated stand-off voltage 12 V. |
| 3 | 3 | passive | Common terminal joining the two TVS diodes from pins 1 and 2 in the pinning diagram. |
