Z4W37V Datasheet, PDF (1/2 Pages) KEC(Korea Electronics) – ZENER DIODE SILICON DIFFUSED-JUNCTION TYPE
SEMICONDUCTOR
TECHNICAL DATA
BEST SUITED FOR OVERVOLTAGE PROTECTION
OF ELECTRONIC SYSTEM :
ELECTRONIC SYSTEM FOR USE IN AUTOMOBILES
ELECTRONIC SYSTEM FOR COMMERCIAL USE
ELECTRONIC SYSTEM FOR INDUSTRIAL USE
FOR COMMUNICATIONS, CONTROLS, MEASURING
INSTRUMENTS, ETC.
FEATURES
Excellent clamp voltage characteristics that protect electronic
system from any kind of surge.
High surge power withstanding capabilities that absorb load dump surge.
Excellent surge responsibility for steep surge absorption.
Surface mount type is available for easy applications.
Zxial lead type is also available.
Although the typical zener voltage is VZ=37V,
we can provide the products other than the typical values.
Corresponds to taping packages. (500P/Reel)
