Zener Diodes
1
Publication date: February 2002 SKE00002BED
MAZ2000 Series (MA2000 Series)
Silicon planar type
For stabilization of power supply
■ Features
•
High reliability, achieved by the combination the planar type and
the glass seal
•
Large power dissipation: P
D
= 1 W
•
Wide voltage range: V
Z
= 5.1 V to 56.0 V
•
Easy-to-use because of the finely divided zener voltage ranks, such
as A and B ranks
