E.S.D NOISE CLIPPING DIODES
NNCD3.3C to NNCD12C
ELECTROSTATIC DISCHARGE NOISE CLIPPING DIODES
(150 mW TYPE)
This product series is a diode developed for E.S.D (Electrostatic
Discharge) noise protection. Based on the IEC1000-4-2 test on
electromagnetic interference (EMI), the diode assures an endur-
ance of no less than 30 kV, thus making itself most suitable for
external interface circuit protection.
Type NNCD3.3C to NNCD12C Series are into 2PIN Ultra Super
Mini Mold Package having allowable power dissipation of 150 mW.
FEATURES
Based on the electrostatic discharge immunity test (IEC1000-4-
2), the product assures the minimum endurance of 30 kV.
Based on the reference supply of the set, the product achieves
a series over a wide range (15 product name lined up).
APPLICATIONS
External interface circuit E.S.D protection.
Circuits for Waveform clipper, Surge absorber.

No part of this document may be copied or reproduced in any form or by any means without the prior written

this document.
NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual property
rights of third parties by or arising from use of a device described herein or any other liability arising from use
of such device. No license, either express, implied or otherwise, is granted under any patents, copyrights or other
intellectual property rights of NEC Corporation or others.
While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices,
the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or
property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety
measures in its design, such as redundancy, fire-containment, and anti-failure features.
NEC devices are classified into the following three quality grades:
"Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a
customer designated "quality assurance program" for a specific application. The recommended applications of
a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device
before using it in a particular application.
Standard: Computers, office equipment, communications equipment, test and measurement equipment,
audio and visual equipment, home electronic appliances, machine tools, personal electronic
equipment and industrial robots
Special:
Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed
for life support)
Specific:
Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life
support systems or medical equipment for life support, etc.
The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books.
If customers intend to use NEC devices for applications other than those specified for Standard quality grade,
they should contact an NEC sales representative in advance.
Anti-radioactive design is not implemented in this product.
