WEE Technology Company Limited
Manufacturer of Surface Mount (SMD) and Through Hole (DIP) Diodes & Rectifiers

Dimension Differentiation of Diode SMA, SMAJ, SMAF, SMB, SMBF, SMC, SMC-S Packages
Taking the common patch Schottky diodes SS14, SS24, SS34 and SS54 as examples, the main differences among the four kinds of diodes are current 1A, 2A, 3A and 5A respectively.
It is different from encapsulation (package) too.
Six packages: SMA, SMAF, SMB, SMBF, SMC, SMC-S. In terms of cost and volume, SMA/SMA-J/DO-214AC packages or SMAF of the smallest size are preferred.
The maximum size is SMC (DO-214AB). In most cases, SMC is the most stable package in electronics circuits

Below is the strong WEET SMC diodes and rectifiers in different series:
