SMBJ11A

Shandong Jingdao Microelectronics · TVS · SMB

SMBJ11A from Shandong Jingdao Microelectronics, in a SMB. 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 Cathode passive Cathode terminal of the unidirectional TVS diode; for this part (SMBJ11A, unidirectional) the datasheet lists a stand-off voltage of 11 V and a 600 W peak pulse power rating at 10/1000 µs.
2 Anode passive Anode terminal of the TVS diode; the datasheet gives an operating junction and storage temperature range of -65 °C to +150 °C.
