Zener Diodes
MAZ2000 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: PD = 1 W
Wide voltage range: VZ = 5.1 V to 56 V
Easy-to-use because of the finely divided zener voltage ranks, such
as A and B ranks
