Product Description
The CM1240 is a 4-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 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.
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-STD883 (Method 3015) specification for Human Body Model
(HBM) ESD, the pins are protected for contact discharges
of greater than ±16kV.
This device is particularly well suited for portable
electronics (e.g. wireless handsets, PDAs, notebook
computers) because of its small package format and easyto-use pin assignments. In particular, the CM1240 is ideal
for protecting USB or mini-USB ports operating at full
speed (12Mbps).
