SR05

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

SR05 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 Bottom rail of the diode array, connected to the TVS diode anode (Pin 1 in the schematic), used as the ground/return reference.
2 I/O1 passive Protected line connected between the upper and lower steering diodes, clamped for 5V operating voltage (VRWM max 5V) with 0.5pF max junction capacitance.
3 I/O2 passive Second protected line connected between the upper and lower steering diodes, clamped for 5V operating voltage (VRWM max 5V) with 0.5pF max junction capacitance.
4 VCC power_in Top rail of the diode array, connected to the TVS diode cathode (Pin 4 in the schematic), taken to the 5V supply or protected line.
