Overview
The MBRM140T3G is a Schottky Power Rectifier produced by onsemi, utilizing the Schottky Barrier principle with a barrier metal and epitaxial construction. This design optimizes the forward voltage drop-reverse current tradeoff, making it highly efficient. The advanced packaging techniques result in a micro miniature, space-saving surface mount rectifier. With its unique heatsink design, the Powermite series offers the same thermal performance as the SMA package but is 50% smaller in footprint area and has one of the lowest height profiles in the industry, at less than 1.1 mm. This component is ideal for use in portable and battery-powered products such as cellular and cordless phones, chargers, notebook computers, printers, PDAs, and PCMCIA cards.
