Zener Diodes
MAZ2000 Series (MA2000 Series)
Silicon planar type
Unit: mm
For stabilization of power supply
• 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 56.0 V
• Easy-to-use because of the finely divided zener voltage ranks, such
as A and B ranks
