KSMBJ5.0A-E3 from KUU, in a SMB. 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 terminal, marked by the color band on the unidirectional device; connects to the positive side of the protected line (stand-off voltage 5.0V, breakdown 6.40-7.00V at 10mA). |
| 2 | A | passive | Anode terminal of the unidirectional TVS diode, connected to the ground/return side of the protected circuit. |
