In Microsemi鈥檚 new Powermite
廬
3
package, these high efficiency ultrafast
rectifiers offer the power handling
capabilities previously found only in
much larger packages. They are ideal
for SMD applications that operate at
high frequencies.
In addition to its size advantages,
Powermite
廬
3 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.
