SESD7L5.0DT5G from onsemi, in a SOT-723. 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 | CATHODE | passive | Cathode of the first uni-directional ESD diode (protects one line, 5.0 V working peak reverse voltage, 0.5 pF typ capacitance to pin 3); pins 1 to 2 form one bi-directional line at 0.25 pF typ. |
| 2 | CATHODE | passive | Cathode of the second uni-directional ESD diode (protects one line, 5.0 V working peak reverse voltage, 0.5 pF typ capacitance to pin 3); pins 1 to 2 form one bi-directional line at 0.25 pF typ. |
| 3 | ANODE | passive | Common anode of both ESD diodes, connected to ground when protecting two uni-directional lines. |
