1.0SMBJ58A

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).
