LC03-3.3 Low Capacitance 3.3 Volt TVS for High Speed Interfaces PROTECTION PRODUCTSPROTECTION PRODUCTS Features Description The LC03-3.3 transient voltage suppressor is designed 1800 watts peak pulse power (t = 8/20s) p to protect components which are connected to high Transient protection for high-speed data lines to speed data and telecommunication lines from voltage Bellcore 1089 (Intra-Building) 100A (2/10s) surges caused by lightning, electrostatic discharge ITU K.20 I =40A (5/310s) PP (ESD), and electrical fast transients (EFT). IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) IEC 61000-4-4 (EFT) 40A (5/50ns) TVS diodes are ideal for use as board level protection IEC 61000-4-5 (Lightning) 100A (8/20s) of sensitive semiconductor components. The LC03- Protects two lines in common and differential mode 3.3 combines a TVS diode with a rectifier bridge to Low capacitance for high-speed interfaces provide transient protection in both common and Low operating voltage (3.3V) differential mode with a single device. The LC03-3.3 Low clamping voltage utilizes Semtechs EPD technology for superior electri- Integrated structure saves board space and cal characteristics at 3.3 volts. The capacitance of the increases reliability device is minimized to ensure correct signal transmis- Solid-state EPD technology sion on high speed lines. Mechanical Characteristics The LC03-3.3 meets the short-haul (intra-building) JEDEC SO-8 package transient immunity requirements of Bellcore 1089 for RoHS/WEEE Compliant telecommunications applications.
