LOW CAPACITANCE HIGH ESD TYPE
ELECTROSTATIC DISCHARGE NOISE CLIPPING DIODES
(QUARTO TYPE: COMMON ANODE)
5-PIN MINI MOLD
This product series is a low capacitance type diode developed for
E.S.D. (Electrostatic Discharge) protection. Based on the
IEC61000-4-2 test on electromagnetic interference (EMI), the diode
assures an endurance of no less than 30 kV, and capacitance is
small with 20 pF TYP. This product series is the most suitable for
the ESD protection in the high-speed data communication bus such
as USB.
With four elements mounted in the 5-PIN Mini Mold Package, that
product can cope with high density assembling.
FEATURES
• Based on the electrostatic discharge immunity test (IEC61000-4-
2), the product assures the minimum endurance of 30 kV.
• Capacitance is small with 20 pF TYP. (at VR = 0 V, f = 1 MHz). It
is excellent in the frequency characteristic.
• With 4 elements mounted (common anode) in the SC-74A
package, that product can cope with high density assembling.
APPLICATIONS
• External interface circuit E.S.D. protection in the high-speed data
communication bus such as USB.

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

• Descriptions of circuits, software, and other related information in this document are provided for illustrative
purposes in semiconductor product operation and application examples. The incorporation of these circuits,
software, and information in the design of the customer's equipment shall be done under the full responsibility
of the customer. NEC Corporation assumes no responsibility for any losses incurred by the customer or third
parties arising from the use of these circuits, software, and information.
• 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: Aircraft, 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.
