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.

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.
