CM1240

Dual-Voltage ESD Protection Array for USB Port

channel of the CM1240 is a high voltage (HV) diode

which has a capacitance of 25pF enabling it to protect

power supply inputs or OLED power rails, etc.

Features

•

4 channels of ESD Protection

•

8kV ESD protection (IEC 61000-4-2, contact

discharge)

The parts integrate avalanche-type ESD diodes, which

provide a very high level of protection for sensitive

electronic components that may be subjected to

electrostatic discharge (ESD). The ESD protection

diodes are designed and characterized to safely

dissipate ESD strikes of 8kV, the maximum

requirement of the IEC61000-4-2 international

standard. Using the MIL-STD-883 (Method 3015)

specification for Human Body Model (HBM) ESD, the

pins are protected for contact discharges of greater

than 16kV.

Applications

•

USB and Mini-USB applications

I/O port protection for mobile handsets

Wireless handsets

This device is particularly well suited for portable

electronics (e.g. wireless handsets, PDAs, notebook

computers) because of its small package format and

easy-to-use pin assignments. In particular, the

CM1240 is ideal for protecting USB or mini USB ports

operating at full speed (12Mbps).

Product Description

California Micro Devices’ CM1240 is a four channel

ESD protection array. Three channels of the CM1240

are low voltage (LV) diodes, which have a capacitance

of 7pF enabling them to protect high speed I/O ports

while providing robust ESD protection. The other

The CM1240 is available in a space saving, low profile,

lead-free TDFN-8 or SOT-563 package.
