Features
Extremely low noise voltage caused from diode (1/3 to 1/10 of
our conventional MAZ4000 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 divided
zener-voltage ranks
Easy-to-mount through the adoption of the small glass-sealed DHD
package (DO-34)
