This document describes the Central Semiconductor CMR1U series of 1.0 Amp Surface Mount Ultra Fast Recovery Silicon Rectifiers. These components are designed for use in commercial, industrial, entertainment, computer, and automotive applications where small size is required. The devices feature a super miniature SMA case that occupies 30% less board space than the SMB case.
