- 07. 22 1/3 SEMICONDUCTOR TECHNICAL DATA Z8W37V ZENER DIODE SILICON DIFFUSED-JUNCTION TYPE Revision No : 0 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
hExcellent clamp voltage characteristics that protect electronic system from any kind of surge. hHigh surge power withstanding capabilities that absorb load dump surge. hExcellent surge responsibility for steep surge absorption. hSurface mount type is available for easy applications. Axial lead type is also available. hAlthough the typical zener voltage is VZ=37V, we can provide the products other than the typical values. hCorresponds to taping packages.
