MAZ4xxxN Series (MA4xxx(N) Series)
Silicon planar type
For stabilization of power supply
■ Features
Extremely low noise voltage caused from diode (1/3 to 1/10 of
our conventional MAZ4xxx series)
Extremely good rising performance (in the low-current range)
Easy-to-identify the zener-voltage rank by the color bands
Easy-to-select the optimum diode because of their finely di-
vided zener-voltage ranks
Easy-to-mount through the adoption of the small glass-sealed
DHD package (DO-34-A2)

within part numbers
Note) 1. Measuring methods are based on JAPANESE INDUSTRIAL STANDARD JIS C 7031 measuring methods for diodes.
2. Absolute frequency of input and output is 50 MHz.
3. *1: The temperature must be controlled 25°C for VZ mesurement.
VZ value measured at other temperature must be adjusted to VZ (25°C)
*2: VZ guaranteed 20 ms after current flow.
*3: Tj
= 25°C to 150°C
