CSPESD304 4-Channel ESD Array in CSP Features • • • • • • Four channels of ESD protection +15kV ESD protection on each channel Product Description The CSPESD304 is a quad ESD transient voltage supression diode array. Each diode provides a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). These diodes are designed and characterized to safely dissipate ESD strikes of 15kV, exceeding the maximum requirement of the IEC 61000-4-2 international standard. Using the MIL-STD-883 (Method 3015) specification for Human Body Model (HBM) ESD, the device provides protection for contact discharges to greater than 30kV. The CSPESD304 is particularly well suited for portable electronics (e.g., cellular telephones, PDAs, notebook computers) because of its small package format and low weight. The CSPESD304 is available in a space-saving, lowprofile Chip Scale Package with optional lead-free finishing. (IEC 61000-4-2 Level 4, contact discharge) +30kV ESD protection on each channel (HBM) Chip Scale Package features extremely low lead inductance for optimum ESD protection 5-bump, 0.950mm X 1.410mm footprint Chip Scale Package (CSP) Lead-free version available Applications • • • • • • • • • ESD protection for sensitive electronic equipment I/O port and keypad and button circuitry protection for portable devices Can be used for EMI filtering when combined with external series resistance Wireless Handsets Handheld PCs / PDAs MP3 Players Digital Camcorders Notebooks Desktop PCs Electrical Schematic ESD_1 ESD_2 ESD_3 ESD_4 C1 C3 A1 A3 GND B2 © 2003 California Micro Devices Corp.
