PROTECTION PRODUCTS - RailClamp(R) Description RailClamp(R) 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 data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (Cable Discharge Events), and EFT (electrical fast transients). The RClamp(R)3624T is specifically designed to protect portable devices that utilize a uUSB port. The unique design of this device features low capacitance TVS diodes for protection of the USB data (DP, DM) and USB ID pins operating up to 5 volts. Loading capacitance on these lines is <1pF for maximum signal integrity. An integrated 28 volt TVS diode is used for protection of the USB voltage bus. This ensures the device will remain in a high-impedance state during normal USB operation or when the battery is being charged. Leakage current of the VBus protection is <250nA when operating at 28 volts. The RCLAMP3624T is in a 6-pin SLP1710P4T package. It measures 1.7 x 1.0 x 0.40mm. The leads are spaced at a pitch of 0.4mm and are finished with leadfree NiPdAu. They may be used to meet the ESD immunity requirements of IEC 61000-4-2.

Low capacitance protection is provided for the USB data (DM, DP) and USB ID pins. The maximum capacitance on these lines is <1pF for maximum signal integrity. USB Data and ID lines are connected at pins 2, 3, and 4. These inputs are referenced to an internal 5 volt TVS protection device. When the voltage on these lines exceed 5 volts, the TVS will conduct. Pin 1 is connected to the USB voltage bus (VBus). This device will conduct when the voltage on the bus exceeds 28 volts. Ground is provided at pins 5 and 6. Note that it is not necessary to connect both ground pins of the device as both are connected internally. Multiple micro vias connected to ground are recommended for best ESD performance. This will reduce parasitic inductance in the ground path and minimize the clamping voltage seen by the protected device. The package is designed for easy trace routing as shown in Figure 2. In this example, the VBus pin is connected to the voltage layer of the PCB with a micro via. Connection to ground is made at pin 6 using two micro vias. Connection to the ID pin is shown, however if the application does not utilize the ID function, pin 4 can be left not connected.
