Surface Mount
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.

* 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
= T
Jmax
- r(t)(Pf + Pr) where
T
J
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 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.
