UM5404
Quad Channel Low Capacitance ESD Protection Array
UM5404EEDF DFN6 1.6×1.6
General Description
UM5404EEDF is 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 over-voltage caused by ESD (electrostatic discharge), electrical fast transients (EFT) and lighting. The unique design 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 supply line or to ground. The internal TVS diode prevents over-voltage on the power line, protecting any downstream components. UM5404EEDF has a low typical capacitance of 1pF and operates with virtually no insertion loss to 2GHz. This makes the device ideal for protection of high-speed data line such as USB2.0, Firewire, DVI and gigabit Ethernet inte.
