MBR120VLSFT1
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.

r(t), TRANSIENT THERMAL RESISTANCE
* 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 = TJmax − 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 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.
