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.

Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits
are exceeded, device functional operation is not implied, damage may occur
and reliability may be affected.
