SMBJ3V3-E3
Vishay Intertech · TVS · SMB(DO-214AA)
SMBJ3V3-E3 from Vishay Intertech, in a SMB(DO-214AA). 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, marked by the color band; connects to the protected 3.3 V line (VWM 3.3 V, VBR 4.1 V at 1.0 mA) of this unidirectional TVS. |
| 2 | A | passive | Anode terminal of the unidirectional TVS, connected to ground/return; peak pulse power 600 W (10/1000 μs). |
