PAKER · TVS · SMB(DO-214AA)
1.0SMBJ58A 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 | K | passive | Cathode of the unidirectional 1.0SMBJ58A, marked by the cathode band, and connected to the protected positive line (reverse stand-off voltage VRWM 58 V, breakdown 64.4 V min to 71.2 V max at 1 mA). |
| 2 | A | passive | Anode of the unidirectional 1.0SMBJ58A, on the side opposite the cathode band, and connected to the return/ground side (rated 1000 W peak pulse power on a 10/1000 µs waveform). |
