DESCRIPTION
APPEARANCE
This Microsemi Powermite® surface mount low noise Zener package series
provides a higher power handling capability that are also RoHS compliant.
In addition to its size advantages, Powermite® 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 efficient heat path
from die to mounting plane for external heat sinking with very low thermal
resistance junction to case (bottom). Its innovative design makes this
DO-216
device ideal for use with automatic insertion equipment.
