CDSOT23-0502B-ES
ElecSuper · ESD And Surge Protection (TVS/ESD) · SOT-23
CDSOT23-0502B-ES from ElecSuper, in a SOT-23. 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 | IO | bidirectional | Connects to an IO data or transmission line, and all pins are rated to withstand ±30 kV IEC61000-4-2 ESD pulses. |
| 2 | IO | bidirectional | Connects to an IO data or transmission line, and all pins are rated to withstand ±30 kV IEC61000-4-2 ESD pulses. |
| 3 | GND | power_in | Connects to ground, serving as the common return for the TVS protection on the IO lines. |
