MAZ4000N Series
(MA4000(N) Series)
Silicon planar type
For stabilization of power supply
s 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-A2)

Please read the following notes before using the datasheets
A. These materials are intended as a reference to assist customers with the selection of Panasonic
semiconductor products best suited to their applications.
Due to modification or other reasons, any information contained in this material, such as available
product types, technical data, and so on, is subject to change without notice.
Customers are advised to contact our semiconductor sales office and obtain the latest information
before starting precise technical research and/or purchasing activities.
B. Panasonic is endeavoring to continually improve the quality and reliability of these materials but
there is always the possibility that further rectifications will be required in the future. Therefore,
Panasonic will not assume any liability for any damages arising from any errors etc. that may ap-
pear in this material.
C. These materials are solely intended for a customer's individual use.
Therefore, without the prior written approval of Panasonic, any other use such as reproducing,
selling, or distributing this material to a third party, via the Internet or in any other way, is prohibited.
Request for your special attention and precautions in using the technical information
and semiconductors described in this material
(1) An export permit needs to be obtained from the competent authorities of the Japanese Govern-
ment if any of the products or technologies described in this material and controlled under the
"Foreign Exchange and Foreign Trade Law" is to be exported or taken out of Japan.
(2) The technical information described in this material is limited to showing representative character-
istics and applied circuit examples of the products. It does not constitute the warranting of industrial
property, the granting of relative rights, or the granting of any license.
(3) The products described in this material are intended to be used for standard applications or gen-
eral electronic equipment (such as office equipment, communications equipment, measuring in-
struments and household appliances).
Consult our sales staff in advance for information on the following applications:
Special applications (such as for airplanes, aerospace, automobiles, traffic control equipment,
combustion equipment, life support systems and safety devices) in which exceptional quality and
reliability are required, or if the failure or malfunction of the products may directly jeopardize life or
harm the human body.
Any applications other than the standard applications intended.
(4) The products and product specifications described in this material are subject to change without
notice for reasons of modification and/or improvement. At the final stage of your design, purchas-
ing, or use of the products, therefore, ask for the most up-to-date Product Standards in advance to
make sure that the latest specifications satisfy your requirements.
(5) When designing your equipment, comply with the guaranteed values, in particular those of maxi-
mum rating, the range of operating power supply voltage and heat radiation characteristics. Other-
wise, we will not be liable for any defect which may arise later in your equipment.
Even when the products are used within the guaranteed values, redundant design is recommended,
so that such equipment may not violate relevant laws or regulations because of the function of our
products.
(6) When using products for which dry packing is required, observe the conditions (including shelf life
and after-unpacking standby time) agreed upon when specification sheets are individually exchanged.
(7) No part of this material may be reprinted or reproduced by any means without written permission
from our company.
