**MCC(Micro Commercial Components)** · Zener Diodes · DO-214AA(SMB)

3SMBJ5930B-TP from MCC(Micro Commercial Components), 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 | K | passive | Cathode, identified by the cathode mark on the SMB package; for the 3SMBJ5930B it is the Zener terminal with VZ = 16 V (±5%) at IZT = 23.4 mA, with maximum IR of 1 µA at VR = 12.2 V. |
| 2 | A | passive | Anode, the terminal opposite the cathode mark; maximum forward voltage is 1.5 V at IF = 200 mA. |
