SMB is a SMD component package commonly used for diodes. The packages other common name is DO-214AA (diode outline 214AA). It is in the same family as SMA (DO-214AC) and SMC (DO-214AB). The common name, SMB, is not to be confused with SMD (surface-mount device, the common name for any surface-mount component).

SMB is relatively easy to solder by hand. Don’t use a really fine tip, as the two pins need a fair amount of heat.

Dimensions

The pitch of the SMB is 3.97mm (center of lead 1 to center of lead 2). The height of the component is 2.44mm.

The SMB package takes up a PCB land area of approximately 22.0mm2(5.59mm×3.94mm)22.0mm^2 (5.59mm \times 3.94mm).
