guard them against the possibility of physical injury, and injury or damage caused by fire in the event of the failure of a

Renesas Electronics product, such as safety design for hardware and software including but not limited to redundancy, fire

control and malfunction prevention, appropriate treatment for aging degradation or any other appropriate measures. Because

the evaluation of microcomputer software alone is very difficult, please evaluate the safety of the final products or system

manufactured by you.

10. Please contact a Renesas Electronics sales office for details as to environmental matters such as the environmental

compatibility of each Renesas Electronics product. Please use Renesas Electronics products in compliance with all applicable

laws and regulations that regulate the inclusion or use of controlled substances, including without limitation, the EU RoHS

Directive. Renesas Electronics assumes no liability for damages or losses occurring as a result of your noncompliance with

applicable laws and regulations.

Suitable device can be selected in three types of NNCD series.

Low capacitance NNCD (8kV/10pF) and Low capacitance High ESD NNCD (30kV/20pF)

are the suitable ESD protection device for high speed data line such as USB 1.1. High

ESD NNCD (30kV) is the suitable device to protect ESD in normal speed data line.

When ESD invades the circuit shown in next figure, EESD (energy of ESD) divides into

ENNCD (energy flowing into NNCD) and Ecircuit (energy flowing into circuit).

EESD=ENNCD+Ecircuit

The impedance of NNCD is smaller than that of the circuit,

ENNCD>>Ecircuit

Most of EESD flows to GND through the NNCD and the circuit can be protected from ESD.

Capacitance

The diode behaves as a capacitor,except during absorbing ESD. In generally the

capacitance increases the rise time and makes some problem. The small capacitance

device is useful to reduce the rise time.

The equivalent circuit of diode

The capacitance of Low Capacitance NNCD series is 10pF or 20pF. These devices give

margin for designing line impedance.

agree and acknowledge that the possibility of defects thereof cannot be eliminated entirely. To minimize

risks of damage to property or injury (including death) to persons arising from defects in NEC

semiconductor products, customers must incorporate sufficient safety measures in their design, such as

redundancy, fire-containment, and anti-failure features.

NEC semiconductor products are classified into the following three quality grades:

"Standard", "Special" and "Specific". The "Specific" quality grade applies only to semiconductor products

developed based on a customer-designated "quality assurance program" for a specific application. The

recommended applications of a semiconductor product depend on its quality grade, as indicated below.

Customers must check the quality grade of each semiconductor product 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 and medical equipment for life support, etc.

The quality grade of NEC semiconductor products is "Standard" unless otherwise expressly specified in NEC's

data sheets or data books, etc. If customers wish to use NEC semiconductor products in applications not

intended by NEC, they must contact an NEC sales representative in advance to determine NEC's willingness

to support a given application.

(Note)

(1) "NEC" as used in this statement means NEC Corporation and also includes its majority-owned subsidiaries.

(2) "NEC semiconductor products" means any semiconductor product developed or manufactured by or for

NEC (as defined above).
