Schottky Power Rectifier POWERMITE®

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.

Features:

•Low Profile – Maximum Height of 1.1 mm

•Small Footprint – Footprint Area of 8.45 mm2

•Low V F Provides Higher Efficiency and Extends Battery Life •Supplied in 12 mm Tape and Reel

•Low Thermal Resistance with Direct Thermal Path of Die on Exposed Cathode Heat Sink

Mechanical Characteristics:

•Powermite is JEDEC Registered as DO–216AA

•Case: Molded Epoxy

•Epoxy Meets UL94V–0 at 1/8″

•Weight: 62 mg (approximately)

•Device Marking: BCV

•Lead and Mounting Surface Temperature for Soldering Purposes. 260°C Maximum for 10 Seconds

* Reverse power dissipation and the possibility of thermal runaway must be considered when operating this device under any re-verse voltage conditions. Calculations of T J therefore must include forward and reverse power effects. The allowable operating T J may be calculated from the equation:T J = T Jmax – r(t)(Pf + Pr) where

r(t) = thermal impedance under given conditions,Pf = forward power dissipation, and Pr = reverse power dissipation

This graph displays the derated allowable T J due to reverse bias under DC conditions only and is calculated as T J = T Jmax – r(t)Pr,where r(t) = Rthja. For other power applications further calculations must be performed.
