BZX84B…Series
SILICON PLANAR ZENER DIODES
This series of Zener diodes is offered in the
convenient, surface mount plastic SOT-23 package.
These devices are designed to provide voltage
regulation with minimum space requirement. They are
well suited for applications such as cellular phones,
hand held portables, and high density PC boards.
