low capacitance tvs array general description SE0504 are surge rated diode arrays designed to protect high speed data interfaces. this series has been specifically designed to protect sensitive components which are connected to data and transmission lines from overvoltage caused by esd (electrostatic dischar ge), cde (cable discharge events), and eft (electrical fast transients). the unique desig n incorporates surge rated, low capacitance steering diodes and a tvs diode in a single package. during transient conditions, the steering diodes direct the transient to either the positive side of the power su pply line or to ground. the internal tvs diode pr events over-voltage on the power line, protecting any downstream components. the low capacitance array configuration allows the user to protect four high-speed data or transmission lines. the low inductance construction minimizes voltage overshoot during high current surges. applications z usb 2.0 z usb otg z monitors and flat panel displays z digital visual interface (dvi) z high-definition multimedia interface (hdmi) z gigabit ethernet z sim ports z ieee 1394 firewire ports features z array of surge rated diodes with internal tvs diode z small package (2.4 x 2.2mm) saves board space z protects up to four i/o lines & power line z low capacitance (<1pf) for high-speed interfaces z no insertion loss to 2.0ghz z low leakage current and clamping voltage z low o perating voltage: 5.0v z solid-state sili con-avalanche technology iec61000-4-2(esd) 15kv(air), 8kv(contact) iec61000-4-4(eft) 40a(5/50ns) iec6100 0-4-5(surg e)24a(8/20us),level2(line-g round)& level 2(line- line) functional diagram sot23-6 willas electronic corp. 2012-09 SE0504 z
