Phoenix, AZ - April 3, 2000 - ON Semiconductor today introduced a new surface mount Powermite Schottky Rectifier with a unique heatsink design that delivers similar thermal performance to the industry standard SMA package. Referred to as the MBRM130LT3, this 1A, 30V device is 50 percent smaller in footprint area than the SMA package which makes it ideal for use in portable and battery powered products such as cellular and cordless phones, battery chargers, notebook computers, printers, PDAs and PCIMCIA cards.
The Schottky Powermite employs the Schottky Barrier principle with a barrier metal and epitaxial construction that produces an optimal tradeoff between forward voltage (Vf) drop and reverse current. Because the device features low Vf, battery life is extended resulting in higher efficiency. The voltage and current specifications are well suited for reverse battery protection in portable applications. Additionally, this device provides a cost-effective transition to a smaller package from an SMB package for applications with power dissipation at or below 1.5W.
The MBRM130LT3 Schottky rectifier measures only 1.1 mm in height and 8.45 mm2 in area. This compact profile and footprint make it an ideal component for applications, where board space is limited. Typical applications are AC/DC and DC/DC converters, reverse battery protection, and "ORing" of multiple supply voltages and any other applications where performance and size are critical.
"Providing packages with smaller footprints is critical to the development of light-weight, portable products," says Collette Hunt, general manager of ON Semiconductor's Bipolar Discretes business unit. "ON Semiconductor plans to pursue further development of smaller size packages to accommodate newer technologies in wireless and handheld products and in designs with limited board space."
Samples and production quantities of the MBRM130LT3 Schottky rectifier are currently available. Pricing in 12K quantities is suggested at a resale value of $0.26.
