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.

1. FR−5 = 1.0 X 0.75 X 0.62 in.

2. Alumina = 0.4 X 0.3 X 0.024 in., 99.5% alumina.
