Dual-Voltage ESD Protection Array for USB Port

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.
