Main product characteristics
Features and benefits
• Low forward voltage drop
• Low profile package height
• Efficient heat path with integral locking bottom metal tab
• Low thermal resistance DO-216AA package
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 TJ therefore must
include forward and reverse power effects. The allowable
operating TJ may be calculated from the equation:
TJ = TJ 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 TJ due to reverse bias
under DC conditions only and is calculated as TJ = TJ max-r(t) Pr,
Where r(t)=Rthja. For other power applications further
calculations must be performed.
