SMAF & SMBF can completely replace all the specifications of the existing SMA& SMB without changing the circuit design and PCB board.
New ultra-thin series products SMAF & SMBF package, on the basis of continuous management and accumulation, we have carried out extensive reforms in the patch aspect. Invest a lot of capital and technology research and development, upgrade traditional products, and realize the real reform of ultra-thin SMAF & SMBF.
The ultra-thin size of the SMAF package can meet the higher requirements of today's rapid technological development of circuit design, and the optimized design of the electrode provides better heat dissipation performance. Using planar technology chips (GPP technology chips and Schottky technology chips), the high temperature reliability of the chips is greatly improved. The thickness is 50% lower than the existing SMA (from 2.2mm to 1.0mm) and thinner than SOP-8 and other ICs. Even if it is mounted on the back of the PCB, it will not be affected at all when the device is cut. The pins are designed with extended pins. The pins are flat on the bottom of the device, which is not easy to deform and damage to avoid the virtual soldering phenomenon caused by the unevenness of the two feet like the SMA flattening process.
SMAF & SMBF chip package covers all types of planar diodes. The size ranges from 24MIL to 70MIL, laying the foundation for the next step of miniaturization and application of ultra-low forward VF series diodes.
