SMBJ36A

Shandong Jingdao Microelectronics · TVS · SMB

SMBJ36A 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 SMBJ36A TVS diode (reverse stand-off voltage VRWM 36 V per Table 1); the PINNING table assigns pin 1 to Cathode for the unipolar (UNI) type.
2 Anode passive Anode terminal of the unidirectional SMBJ36A TVS diode, which clamps transient overvoltages on the line (peak pulse power 600 W at 10/1000 µs); the PINNING table assigns pin 2 to Anode for the unipolar (UNI) type.
