CM1240 Dual-Voltage ESD Protection Array for USB Ports 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 7 pF 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 25 pF 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 ±8 kV, 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 ±16 kV. 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 (12 Mbps).
