ESD4-DFN LOW CAPACITANCE TVS ARRAY PIN CONFIGURATION

Transcription

1 LOW CAPACITANCE TVS ARRAY Description The is a multi-line, low capacitance, 2.5V bias transient voltage suppressor array. This device is designed to protect applications such as wireless telecommunication devices, PCMCIA cards and other portable electronics from the damaging effects of ESD and EFT. DFN-4 package The has a working voltage of 5.0V and a minimum breakdown voltage of 6.0V. The is ideally suited to protect 5V DC lines and data I/O ports against ESD and EFT and meets IEC (ESD) and IEC (EFT) requirements. At higher operating frequencies or faster edge rates, insertion loss and signal integrity are a major concern. Packaged in the DFN-4 plastic case, the should be placed near the connector to provide maximum protection. Features applications Compatible with IEC (ESD): Air - 15kV, Contact - 8kV Compatible with IEC (EFT): 40A - 5/50ns 25 Watts Peak Pulse Power per Line (tp = 8/20µs) ESD Protection > 25 kilovolts Protects up to 4 Data Lines RoHS Compliant REACH Compliant SMART Phones LCD Display Panel Portable Electronics SMART Cards Mechanical characteristics Molded JEDEC DFN-4 Package Approximate Weight: 2 milligrams Lead-Free Nickel Paladium Gold Solder Reflow Temperature: Nickel-Paladium-Gold: Ni/Pd/Au, 96/3.5/0.5: C 8mm Tape and Reel Per EIA Standard 481 Flammability Rating UL 94V-0 PIN CONFIGURATION R2 9/12 Page 1
