Description and applications
Single schottky rectifier assembled in Powermite 1
®
package which features a full metallic bottom that
eliminates possibility of solder flux entrapment during assembly. The package also incorporates a unique
locking tab which acts as an efficient heat path from die to mounting plane for external heat sinking with
very low thermal resistance junction to case (bottom).
This product is suitable for use in switching and regulating power supplies and also charge pump
circuits.

Reverse power dissipation and the possibility of thermal runaway
must be considered when operating this device under any
reverse 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
J max
= 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 de-rated allowable T
J
due to reverse bias
under DC conditions only and is calculated as T
J
= T
J max
-r(t) Pr,
Where r(t)=Rthja. For other power applications further
calculations must be performed.
