CM1204 4-Channel ESD Array in CSP Product Description The CM1204 is a quad ESD transient voltage suppression 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 safely dissipate ESD strikes of 15 kV, 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 30 kV. The CM1204 is particularly well suited for portable electronics (e.g., cellular telephones, PDAs, notebook computers) because of its small package format and low weight. The CM1204 features Optiguardt coating which results in improved reliability at assembly. It is available in a space-saving, low-profile chip scale package with RoHS-compliant lead-free finishing. http://onsemi.com CSP-5 CP SUFFIX CASE 567AY BLOCK DIAGRAM ESD_1 ESD_2 ESD_3 A1 A3 C1 ESD_4 C3 Features * Functionally and Pin Compatible with ON Semiconductor's * * * * * * * CSPESD304 Optiguardt Coated for Improved Reliability Four Channels of ESD Protection 15 kV ESD Protection on Each Channel (IEC 61000-4-2 Level 4, Contact Discharge) 30 kV ESD Protection on Each Channel (HBM) Chip Scale Package Features Extremely Low Lead Inductance for Optimum ESD Protection 5-bump, 0.960 mm X 1.330 mm Footprint Chip Scale Package (CSP) These Devices are Pb-Free and are RoHS Compliant S S Protection for Portable Devices Wireless Handsets Handheld PCs / PDAs MP3 Players Digital Camcorders Notebooks Desktop PCs January, 2011 - Rev. 4 = Specific Device Code ORDERING INFORMATION * ESD Protection for Sensitive Electronic Equipment * I/O Port and Keypad and Button Circuitry (c) Semiconductor Components Industries, LLC, 2011 B2 MARKING DIAGRAM Applications * * * * * * GND Device Package Shipping CM1204-03CP CSP (Pb-Free) 3500/Tape & Reel For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specification Brochure, BRD8011/D. 1 Publication Order Number: CM1204/D CM1204 PACKAGE / PINOUT DIAGRAMS Table 1.
