Diodes - Rectifiers - Arrays: SBG3040CT-T-F Application Field and Working Principle

Arrays such as SBG3040CT-T-F are essential for a variety of semiconductor applications due to their rectifier capabilities and robustness. This product consists of four Schottky diodes integrated in an ultra-small DFN package. The total forward voltage drop of each diode is typcially around 0.3V. The low profile package makes it ideal for space-conscious applications, while the low on-state resistance (RON) of each diode contributes to low power consumption. This makes SBG3040CT-T-F suitable for point of load (POL) applications.

Furthermore, SBG3040CT-T-F is optimized as a synchronous rectifier in transformer/transformer or transformer/inductor based isolated power converters. The low forward voltage drop translates to better efficiency and higher power density, which is an invaluable benefit in POE applications. Consequently, SBG3040CT-T-F is the ideal choice for AC/DC, DCC, and Power over Ethernet (PoE++) applications.

Working Principle

The operation of SBG3040CT-T-F is based on a three-phase bridge rectifier. At any instant, two of the four diodes in the bridge are in forward bias, allowing current to flow through them. The other two diodes are in reverse bias, blocking current from passing through them. As the phase of the input voltage changes, the two diodes in forward bias also change, resulting in semi-controlled current rectification. Moreover, the four integrated diodes reduce the conduction losses associated with four independent diodes.

Package Details

The Schottky Barrier Rectifier Array family of components includes a variety of packages to suit the needs of various applications. The flagship SBG3040CT-T-F packages integrated Schottky diodes in a reduced size Quad Flat No Lead (DFN) form factor with a Gull-wing lead (E2) footprint. It measures 2.1 mm x 1.4 mm x 0.8 mm, making it ideal for space-constrained applications. The package provides excellent thermal performance, allowing for reliable operation even in high power applications.
