| MBRM140 Surface Mount Schottky Power Rectifier POWERMITE(R) Power Surface Mount Package The Schottky Powermite employs the Schottky Barrier principle with a barrier metal and epitaxial construction that produces optimal forward voltage drop- reverse current tradeoff. The advanced packaging techniques provide for a highly efficient micro miniature, space saving surface mount Rectifier. With its unique heatsink design, the Powermite has the same thermal performance as the SMA while being 50% smaller in footprint area, and delivering one of the lowest height profiles, < 1.1 mm in the industry. Because of its small size, it is ideal for use in portable and battery powered products such as cellular and cordless phones, chargers, notebook computers, printers, PDAs and PCMCIA cards. Typical applications are ac/dc and dc-dc converters, reverse battery protection, and "Oring" of multiple supply voltages and any other application where performance and size are critical.

Typical Operating Temperature Derating* * Reverse power dissipation and the possibility of thermal runaway must be considered when operating this device under any reverse voltage conditions. Calculations of TJ therefore must include forward and reverse power effects. The allowable operating TJ = TJmax - r(t)(Pf + Pr) where TJ may be calculated from the equation: r(t) = thermal impedance under given conditions, Pf = forward power dissipation, and Pr = reverse power dissipation This graph displays the derated allowable TJ due to reverse bias under DC conditions only and is calculated as TJ = TJmax - r(t)Pr, where r(t) = Rthja. For other power applications further calculations must be performed. http://onsemi.com 4 MBRM140 R(T), TRANSIENT THERMAL RESISTANCE (NORMALIZED) 1.0 50% 0.1 20% 10% 5.0% 0.01 2.0% 1.0% Rtjl(t) = Rtjl*r(t) 0.001 0.00001 0.0001 0.001 0.01 T, TIME (s) 0.1 1.0 10 100 Figure 9.
