1SMB3EZ16_R1_00001 from PANJIT International, in a DO-214AA(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 of the zener diode; the color band on the package denotes the cathode end, and the device is rated for 3 W steady-state power dissipation at TL = 75 °C (mounted on infinite heatsink). |
| 2 | Anode | passive | Anode terminal of the zener diode, with the device operating junction and storage temperature range stated as -55 °C to +150 °C. |
