Zener Diodes
MAZ2000 Series
(MA2000 Series)
Silicon planar type
Unit: mm
For stabilization of power supply
s
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
