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 siliconoxide passivated junctions. All this in an axiallead,
transfermolded 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 Pbfree package(s). Specifications herein
apply to both standard and Pbfree devices. Please see our website at
www.onsemi.com for specific Pbfree orderable part numbers, or
contact your local ON Semiconductor sales office or representative.
Mechanical Characteristics:
CASE: Void free, transfermolded, thermosetting plastic
FINISH: All external surfaces are corrosion resistant and leads are
readily solderable
MAXIMUM LEAD TEMPERATURE FOR SOLDERING PURPOSES:
230°C, 1/16from the case for 10 seconds
POLARITY: Cathode indicated by polarity band
MOUNTING POSITION: Any
