TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT353
TPRCLAMP0503F from TECH PUBLIC, in a SOT353. 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 | IO1 | passive | ESD-protected I/O line 1 (steering diode pair to pin 5 and GND), with I/O-to-GND capacitance of 1.0 pF max and I/O-to-I/O 0.5 pF typ. |
| 2 | GND | power_in | Ground reference of the TVS array, connected to the cathode side of the lower steering diodes and the TVS diode. |
| 3 | IO2 | passive | ESD-protected I/O line 2 (steering diode pair to pin 5 and GND), protected to IEC 61000-4-2 ±25kV air and ±20kV contact. |
| 4 | IO3 | passive | ESD-protected I/O line 3 (steering diode pair to pin 5 and GND), clamping at 15V max at 1A (8/20µs). |
| 5 | VCC | power_in | Positive rail of the steering diodes and TVS cathode, with reverse working voltage of 5V max and breakdown of 6V min at 1mA. |
