MICROSEMI UPS340

UPS340
3 A LOW Vf Schottky Barrier Rectifier
KEY FEATURES
DESCRIPTION
In addition to its size advantages,
Powermite3® package features include a full
metallic bottom that eliminates the
possibility of solder flux entrapment during
assembly, and a unique locking tab acts as
an integral heat sink. Its innovative design
makes this device ideal for use with
automatic insertion equipment.

In Microsemi’s new Powermite3® SMT
package, these high efficiency ultrafast
rectifiers offer the power handing
capabilities previously found only in
much larger packages. They are ideal
for SMD applications that operate at
high frequencies.
! High power surface mount
package.
! Guard Ring die construction for
transient protection.
! Silicon Schottky rectifiers no
reverse voltage recovery.
! Internal heat sink locking tabs
! Low forward voltage.
! Full metallic bottom eliminates
flux entrapment
! Compatible with automatic
insertion equipment
! Low profile-maximum height of
1mm supplied in 16 mm tape
reel- 5000 units/ 13” reel.
