PSR05 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 | GND | power_in | Ground reference for the TVS diode array; the I/O clamp diodes steer surge current to this pin. |
| 2 | I/O1 | passive | Protected I/O line 1 with 0.9 pF max junction capacitance to GND (VR=0V, f=1MHz), rated for 5V reverse working voltage and ±30kV IEC 61000-4-2 ESD. |
| 3 | I/O2 | passive | Protected I/O line 2 with 0.9 pF max junction capacitance to GND (VR=0V, f=1MHz), rated for 5V reverse working voltage and ±30kV IEC 61000-4-2 ESD. |
| 4 | VCC | power_in | Positive supply rail reference of the diode array, connects to the steering diodes and the internal TVS diode, operating voltage 5V. |
