CM1209 Datasheet | California Micro Devices

Features - - - - - - - Four, six or eight channels of ESD protection for high data rate signals Zener diode protects supply rail and eliminates the need for external by-pass capacitors +15 k V contact, +15 k V air ESD protection per channel (IEC 61000-4-2 standard) Low loading capacitance of 6p F typical Low supply current Available in miniature MSOP and SOIC packages Lead-free versions available Product Description The CM1209 family of diode arrays are designed to provide either 4, 6 or 8 channels of ESD protection for electronic ponents or sub-systems. Each channel consists of a pair of diodes which steer the ESD current pulse either to the positive (VP) or negative (VN) supply. In addition, there is an integral Zener diode between VP and VN to suppress any voltage disturbance due to these ESD current pulses. The CM1209 devices will protect against ESD pulses up to 15k V contact discharge per the International Standard IEC61000-4-2. These devices are particularly well-suited for portable electronics (e.g. cellular phones, PDAs, notebook puters) because of its small package footprint, high ESD protection level, and low loading capacitance. They are also suitable for protecting video output lines and I/O ports in puters, set top boxes, digital TVs and peripheral equipment. The CM1209 family of devices is optionally available with lead-free finishing.
