Zener Diodes
MAZ1000 Series (MA1000 )Series
Silicon planar type
For stabilization of power supply
Unit : mm
I Features
High reliability, achieved by the combination the planar type and
the glass seal
Large power dissipation: PD = 500 mW (With a printed-circuit
board)
Wide voltage range: VZ = 2.0 V to 39 V
Easy-to-use because of the finely divided zener voltage ranks, such
as L, M, and H ranks
Sharp rising performance
