SS22B

Shandong Jingdao Microelectronics · Schottky Diodes · SMB

SS22B 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 SS22B Schottky barrier rectifier; the datasheet states no pin-specific electrical limits beyond the device ratings (VRRM 20 V, IF(AV) 2.0 A).
2 Anode passive Anode terminal of the SS22B Schottky barrier rectifier; the datasheet states no pin-specific electrical limits beyond the device ratings (VRRM 20 V, IF(AV) 2.0 A).

CAD (KiCad official)

  • Symbol: SS22B
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: ss22b-etched.step / ss22b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ss22b.step / ss22b.glb are the bare package body.
