TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-523
TPSP0502BXTG from TECH PUBLIC, in a SOT-523. 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 | Protected I/O line 1 (TVS diode to common pin 3), with 5V max reverse working voltage, 6V min breakdown at 1mA, and 0.6pF max capacitance to ground. |
| 2 | I/O2 | passive | Protected I/O line 2 (TVS diode to common pin 3), with 5V max reverse working voltage, 6V min breakdown at 1mA, and 0.6pF max capacitance to ground. |
| 3 | GND | power_in | Common ground pin shared by both TVS diodes, which are rated for ±20kV air and ±15kV contact ESD per IEC 61000-4-2. |
