Zener Voltage Regulators
225 mW SOT−23 Surface Mount
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.

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
