Surface Mount Schottky Power Rectifier

Plastic SOD−123 Package

This device uses 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.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected.

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 may be calculated from the equation: TJ = T

− r(t)(Pf + Pr) where

Jmax

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 = T where r(t) = Rthja. For other power applications further calculations must be performed.
