POWERMITETM
Low Noise 1 Watt Zener Diodes
DESCRIPTION
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 device ideal for use with automatic insertion
equipment.
