Zener Voltage Regulators
300 mW SOD−323 Surface Mount
Tight Tolerance Portfolio
MM3ZxxxST1G Series,
SZMM3ZxxxST1G Series
This series of Zener diodes is packaged in a SOD−323 surface
mount package that has a power dissipation of 300 mW. They are
designed to provide voltage regulation protection and are especially
attractive in situations where space is at a premium. They are well
suited for applications such as cellular phones, hand−held portables,
and high density PC boards.
