SMBJ15CA-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 | Terminal 1 | passive | First terminal of the bi-directional TVS (CA suffix); electrical characteristics apply in both directions, there is no cathode band or polarity marking, and the part is rated 600 W peak pulse power (10/1000 μs). |
| 2 | Terminal 2 | passive | Second terminal of the bi-directional TVS (CA suffix); interchangeable with terminal 1 since electrical characteristics apply in both directions, with the SMBJ15CA stand-off voltage VWM of 15 V. |
