| USB Downstream Port Terminator with VBUS ESD Protection PACUSBVB-D1/D2/D3 Features * A low-capacitance USB downstream port terminator, EMI filter, and transient over-voltage protector in a single surface-mounted package ESD protection to 20kV contact discharge, per MIL-STD-883D, Method 3015 ESD protection to 15kV contact discharge, per IEC 61000-4-2 International Standard Provides ESD protection for the VBUS line Compact SOT23-6 package saves board space and lowers manufacturing costs compared to discrete solutions Capacitors matched to a precision exceeding the USB specification Lead-free versions available Product Description The PACUSBVB-D1/D2/D3 is a single-channel USB downstream-port termination network. It integrates EMI/RFI filter components R1 and C1 as recommended by the USB specification, as well as the required 15kW pull-down resistors (R2) to GND. In addition, PACUSBVB-D1/D2/D3 provides a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The device pins will safely dissipate ESD strikes of 15kV, exceeding the maximum requirements of the IEC 61000-4-2 international standard. Using the MIL-STD-883D (Method 3015) specification for Human Body Model (HBM) ESD, all pins are protected from contact discharges to 20kV. The PACUSBVB-D1/D2/D3 also features a fifth zener diode (cathode at pin 5) which provides ESD protection for the USB VBUS line. There are three options for the value of the series resistor R1: 15, 33, and 22. This series resistance, plus the USB driver output resistance, must be close to the USB cable's characteristic impedance of 45W (each side) to minimize transmission line reflections. The PACUSBVB-D1/D2/D3 is housed in a 6-pin SOT23 package and is available with optional leadfree finishing. * * * * * * Applications * * * * * ESD protection and termination of USB downstream ports Desktop PCs Notebooks Set-top boxes USB hubs (c)2010 SCILLC.

Note 2: Pins 1 and 3 are not connected to the USB port connector, and therefore are not exposed to external ESD hazards. Thus, they do not require the high ESD protection levels provided for pins 4, 5, and 6. Note 3: ESD Clamping Voltage is measured at the opposite end of R1 from the pin to which the ESD discharge is applied (e.g., if ESD is applied to pin 6, then the clamping voltage is measured at pin 1).

It integrates the series resistors (R1) and the 15kW pull-down resistors (R2) for both USB data lines (D+ and D-) as well as the capacitors to ground for EMI suppression. Zener diodes provide ESD protection up to 15kV contact discharge per the IEC 61000-4-2 standard and protect the USB controller on both data lines. The 6-lead PACUSBVB-D1/D2/D3 device provides an additional zener diode to protect the VBUS USB power line. The PACUSBVB-D1/D2/D3 should be placed on the PCB between the USB controller and the USB connector, as shown on the Connection Diagram Connection Diagram for PACUSBVB-D1/D2/D3. Figure 5. Connection Diagram for PACUSBVB-D1/D2/D3 To guarantee the best ESD and filtering performance, it is recommended that the PACUSBVB-D1/D2/D3 be located close to the USB connector. Also, the trace lengths between the PACUSBVB-D1/D2/D3 and the USB controller should be kept as short as possible.
