Surface Mount

Schottky Power Rectifier Plastic SOD−123 Package

...using the Schottky Barrier principle with a large area metal−to−silicon power diode. Ideally suited for low voltage, high frequency rectification or as free wheeling and polarity protection diodes in surface mount applications where compact size and weight are critical to the system. This package also provides an easy to work with alternative to leadless 34 package style. 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. These state−of−the−art devices have the following features:•Guardring for Stress Protection

•Low Forward V oltage

•125°C Operating Junction Temperature

•Epoxy Meets UL94, V0 at 1/8″

•Package Designed for Optimal Automated Board Assembly •ESD Ratings: Machine Model, C

* 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.
