TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-23-3
TPESD112-B1-02ELS from TECH PUBLIC, in a SOT-23-3. 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 | Terminal 1 of the 1-line ESD protection diode, shown on the pin configuration diagram with a chamfered pad corner; protects against IEC 61000-4-2 ±18kV air and ±12kV contact discharge, with 5V reverse working voltage. |
| 2 | 2 | passive | Terminal 2 of the 1-line ESD protection diode, connected through the diode symbol to terminal 1; 0.2 pF typical junction capacitance at VR = 0V, f = 1MHz. |
| 3 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
