Comchip’s flat chip packages are available in a variety of sizes and electrical properties. Four types of diodes come in DFN/QFN flat chip packages: small signal switching diodes (current up to 0.5A), small signal Schottky diodes (current up to 0.5A), ESD suppressors for surge protection, small signal Zener diodes (rated power 200mW), as the size of the flat chip packages decreases, so does the rated power of each smaller package. There are four flat chip DFN packages to choose from: SOD-323F (similar to the SOD-323, 1005 dimension, ‘F’ or ‘FR’ package code), SOD-523F (similar to SOD-523, 0603 dimension, ‘U’ or ‘UR’ package code), SOD-723F (similar to SOD-723, 0503 dimension, ‘ER’ package code), SOD-923F (similar to SOD-923, 0402 dimension, ‘QR’ package code).
