Zener Voltage Regulators
200 mW SOD-323 Surface Mount
This series of Zener diodes is packaged in a SOD–323 surface mount package that
has a power dissipation of 200 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.

Notes) 1. The Zener voltage (V
z
) is measured 40ms after power is supplied.
2. The operating resistances (Z
z
, Z
zk
) are measured by superimposing a minute alternating current on the regulated current (I
z
).
