SESR05 from SEMIWARE, 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 of the steering-diode array, connected to the diode network on the pin configuration diagram. |
| 2 | I/O | passive | Protected I/O line 1 (steering diodes to REF and GND); IR max 1 uA at VRWM 5.0 V, CT(I/O-GND) typ 2.0 pF. |
| 3 | I/O | passive | Protected I/O line 2 (steering diodes to REF and GND); IR max 1 uA at VRWM 5.0 V, CT(I/O-I/O) typ 1.0 pF. |
| 4 | REF | passive | Reference pin connected to the TVS avalanche diode of the array, with breakdown VB min 6.0 V at 1 mA. |
