# SMBJ16A-TP

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

SMBJ16A-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 (positive end, marked by color band) of the unidirectional TVS; SMBJ16A has VWM 16V, V(BR) 17.8-19.7V at 1mA and max clamping 26.0V at 23.1A IPP. |
| 2 | A | passive | Anode of the unidirectional TVS, the end opposite the color band; peak pulse power 600W on 10/1000us waveform. |
