UCLAMP3304A General Description

DescriptionThe µClampTM series of TVS arrays are designed to protect sensitive electronics from damage or latch-up due to ESD. They are designed for use in applications where board space is at a premium. Each device requires less than 2.9mm2 of PCB area and will protect up to four lines. They are unidirectional devices and may be used on lines with positive signal polarities.Features◆ Transient protection for data lines to IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact) IEC 61000-4-4 (EFT) 40A (5/50ns)◆ Protects four unidirectional I/O lines◆ Ultra-small SC-89 package (1.7 x 1.7 x 0.6mm) requires less than 2.9mm2 of PCB area◆ Working voltage: 3.3V◆ Low leakage current◆ Low operating and clamping voltages◆ Solid-state silicon-avalanche technologyApplications◆ Cellular Handsets and Accessories◆ Cordless Phones◆ Notebooks and Handhelds◆ Portable Instrumentation◆ Digital Cameras◆ Peripherals◆ MP3 Players
