3EZ4.3D5 Series
3 Watt DO−41 SurmeticE 30
Zener Voltage Regulators
This is a complete series of 3 Watt Zener diodes with limits and
excellent operating characteristics that reflect the superior capabilities
of silicon−oxide passivated junctions. All this in an axial−lead,
transfer−molded plastic package that offers protection in all common
environmental conditions.
Specification Features:
• Zener Voltage Range − 4.3 V to 330 V
• ESD Rating of Class 3 (>16 KV) per Human Body Model
• Surge Rating of 98 W @ 1 ms
• Maximum Limits Guaranteed on up to Six Electrical Parameters
• Package No Larger than the Conventional 1 Watt Package
w These devices are available in Pb−free package(s). Specifications herein
apply to both standard and Pb−free devices. Please see our website at
