1.0SMBJ24CA from PAKER, 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 | A1 | passive | Bi-directional TVS terminal (no cathode band, no polarity) for the 24 V VRWM CA device, with 1000W 10/1000us peak pulse power. |
| 2 | A2 | passive | Bi-directional TVS terminal (no cathode band, no polarity) for the 24 V VRWM CA device, interchangeable with the other terminal. |
