PSR05

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-143

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.

  • Symbol: PSR05
  • Footprint: Package_TO_SOT_SMD:SOT-143
  • 3D model: SOT-143 (KiCad packages3D, STEP)
  • 3D model files: psr05-etched.step / psr05-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); psr05.step / psr05.glb are the bare package body.
