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. |
