SMAJ3.3A from BORN, in a SMA(DO-214AC). 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 | K | passive | Cathode of the unidirectional SMAJ3.3A, marked by the band on the package, connected to the positive side with a 3.3V reverse stand-off voltage and 4.20V to 6.55V breakdown at 1.0mA. |
| 2 | A | passive | Anode of the unidirectional SMAJ3.3A, the unbanded end, which is the return side and conducts forward with VF of 5.0V max at 25A. |
