Image of Vishay Semi Diodes Surface-Mount Standard and TMBS® Rectifiers Vishay offers 27 standard and trench MOS barrier Schottky (TMBS^®) surface-mount rectifiers in a low-profile DFN33A package with wettable flanks. Providing space-saving, high-efficiency solutions for commercial, industrial, telecom, and automotive applications, the standard devices provide current ratings up to 6 A, while the TMBS devices deliver current ratings up to 9 A. Compared to the conventional SMB (DO-214AA) and eSMP^® series SMPA (DO-220AA), the DFN33A package is 44% and 20% smaller, respectively. The devices’ low profile is 2.6 times thinner than the SMB (DO-214AA) and SMC and 7% thinner than the SMPA (DO-220AA). The rectifiers’ optimized copper mass design and advanced die placement technology allow for superior thermal performance that enables operation at higher current ratings.

Features

High current ratings up to:
- 6 A for standard rectifiers
