RClamp0582N RailClamp® Low Capacitance TVS Diode Array PROTECTION PRODUCTS - RailClamp® Description Features ESD protection for high-speed data lines to RailClamp® TVS arrays are ultra low capacitance ESD protection devices designed to protect high speed data interfaces. This series has been specifically designed to protect sensitive components which are connected to high-speed data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (Cable Discharge Events), and EFT (electrical fast transients). The monolithic design incorporates surge rated, low capacitance steering diodes and a TVS diode in a single package. Each line has a typical capacitance of <0.2pF to ground. The capacitance of each line is well matched for consistant signal balance. A connection to the TVS is provided for protection of external voltage buses, such as those found in USB applications. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (±15kV air, ±8kV contact discharge). The RClamp®0582N is qualified to AEC-Q100 Grade1 (-40 to +125oC) and is supplied in a 6-pin SLP1210N6 package. It measures 1.2 x 1.0 x 0.58mm.

Pin 1 is connected to ground. Note that the circuit at the ground pin is identical to the circuit at each data input/output pin. This is done to further reduce capacitance. The connection to ground should be made directly to a ground plane. The path length should also be kept as short as possible to minimize parasitic inductance. Pin 6 can be connected to Vcc biased or left not connected depending upon the application. 6 1 4 5 Figure 2 - USB 2.0 High Speed Protection Protecting USB 2.0 Interfaces The USB interface consists of Data (D- and D+) lines and a 5.25V voltage bus. Since these pins are part of the connector, they are vulnerable to ESD and cable discharge events. The RClamp0582NQ is designed to protect all four USB connections (VCC, D-, D+, and Gnd). Each device will protect one USB port. When the voltage on the data lines exceed the bus voltage (plus one diode drop), the internal rectifiers are forward biased conducting the transient current away from the protected controller chip. The TVS diode directs the surge to ground. The TVS diode also acts to suppress ESD strikes directly on the voltage bus. Thus, both power and data pins are protected with a single device.
