TPESD05V14T-LC from TECH PUBLIC, in a SOT-143. 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 | Common rail at the bottom of the diode bridge, joined to the TVS diode on the pin 1 side; the datasheet gives it no name or function label. |
| 2 | 2 | passive | Protected line connected to the midpoint of one steering-diode pair between pin 4 and pin 1; the datasheet gives it no name. |
| 3 | 3 | passive | Protected line connected to the midpoint of the second steering-diode pair between pin 4 and pin 1; the datasheet gives it no name. |
| 4 | 4 | passive | Common rail at the top of the diode bridge, joined to the TVS diode on the pin 4 side; the datasheet gives it no name or function label. |
