RClamp3654PA RailClamp(R) Low Capacitance TVS Array PROTECTION PRODUCTS - RailClamp(R) Description Features Transient protection for high-speed data lines to 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 high-speed data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (Cable Discharge Events), and EFT (electrical fast transients). The RClamp(R)3654PA is specifically designed to protect portable devices that utilize the USB port for battery charging. The unique design of this device features low capacitance TVS diodes for protection of the USB data (DP, DM) and USB ID (accessory detect) 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 <100nA when operating at 28 volts. The RClamp3654PA is in a 6-pin SLP1616P6 package. It measures 1.6 x 1.6 x 0.60mm. The leads are spaced at a pitch of 0.5mm and are finished with leadfree NiPdAu. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (15kV air, 8kV contact discharge).

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 6 is connected to the USB voltage bus (VBus). This device will conduct when the voltage on the bus exceeds 28 volts. The center tab is connected to ground. The path length should also be kept as short as possible to minimize parasitic inductance. For best results, multiple micro-vias are recommended to the ground plane. 6 1 2 3 5.5V 28V GND Protecting USB Interfaces The RClamp3654PA is optimized for use on systems that utilize the USB interface for battery charging. 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. All three lines are referenced to an internal 5 volt TVS device. A separate 28 volt TVS device is used for protection of the USB voltage bus. This allows battery charging without signal clipping.
