Revision 04/19/2010

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 overvolt-

age caused by ESD (electrostatic discharge), CDE

(Cable Discharge Events), and EFT (electrical fast

transients).

The RClamp®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 lead-

free NiPdAu. They may be used to meet the ESD

immunity requirements of IEC 61000-4-2, Level 4

(15kV air, 8kV contact discharge).

Figure 1- Pin Configuration & Circuit Diagram

Device Connection Options for Protecting One USB

Port

USB Data and ID lines are connected at pins 1, 2, and

3. 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.

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. A typical example is

shown in Figure 2.
