This Dual TSOP-6 package is ideal for applications where
printed circuit board space is at a premium and where

TSOP-6

maximum functionality is required. With two die per
package, the IRF5850 can provide the functionality of two
SOT-23 packages in a smaller footprint. Its unique thermal
design and R

reduction enables an increase in

DS(on)

current-handling capability.
