SMAJ4742A-TP from MCC Micro Commercial Components, 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, the end marked with the cathode band; positive side in zener breakdown, with VZ 12V ±5% at IZT=21mA for SMAJ4742A and max forward voltage 1.2V at IF=100mA. |
| 2 | A | passive | Anode, the end opposite the cathode band; power dissipation is limited to 1.0W at TA≤50°C and junction temperature range is -65°C to +150°C. |
