Maximum Steady State Power Dissipation

Thermal Resistance from Junction−to−Ambient

Operating and Storage

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.

This complete new line of 3 Watt Zener diodes offers the following

readily solderable

260 C for 10 Seconds

Zener Voltage Range − 3.3 V to 200 V

ESD Rating of Class 3 (>16 kV) per Human Body Model

Flat Handling Surface for Accurate Placement

Package Design for Top Side or Bottom Circuit Board Mounting

Pb−Free Packages are Available
