ElecSuper · ESD And Surge Protection (TVS/ESD) · SOT-523
RClAMP0502B-ES from ElecSuper, in a SOT-523. 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 | Connect to IO, one of the two protected data lines; the array clamps ESD up to ±15 kV (IEC 61000-4-2 contact and air) with a 5.0 V peak reverse working voltage. |
| 2 | IO | bidirectional | Connect to IO, the second protected data line; the array clamps ESD up to ±15 kV (IEC 61000-4-2 contact and air) with a 5.0 V peak reverse working voltage. |
| 3 | GND | power_in | Connect to GND as the common reference for the TVS array. |
