ESDA25SC6 from STMicroelectronics, in a SOT-23-6L. 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 | IO1 | passive | I/O signal line 1; anode of unidirectional Transil TVS diode 1; cathode side exits at pin 6 (GND); VBR min 25 V, VBR max 30 V, VCL max 51 V at IPP 9 A (8/20 µs), peak pulse power 400 W. |
| 2 | IO2 | passive | I/O signal line 2; anode of unidirectional Transil TVS diode 2; cathode side exits at pin 5 (GND); same VBR and clamping ratings as pin 1. |
| 3 | IO3 | passive | I/O signal line 3; anode of unidirectional Transil TVS diode 3; cathode side exits at pin 4 (GND); same VBR and clamping ratings as pin 1. |
| 4 | GND | power_in | Ground reference; cathode of TVS diode 3 (paired with IO pin 3); connect to board GND; IRM leakage max 1 µA at VRM 24 V. |
| 5 | GND | power_in | Ground reference; cathode of TVS diode 2 (paired with IO pin 2); connect to board GND; shares the same IRM leakage spec as pin 4. |
| 6 | GND | power_in | Ground reference; cathode of TVS diode 1 (paired with IO pin 1); connect to board GND; shares the same IRM leakage spec as pin 4. |
