| USB Downstream Port Terminator PACUSB-D1/D2/D3 Features * A low-capacitance USB downstream port terminator, EMI filter, and transient over-voltage (ESD) 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 Compact SOT23-5 and SC70-5 package options save board space and lower manufacturing costs compared to discrete solutions Capacitors matched to a precision exceeding the USB specification Pin-compatible with ST Microelectronics USBDFxxW5 USB Downstream Port Terminator Lead-free versions available Product Description The PACUSB-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, PACUSB-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. There are three options for the value of the series resistor R1: 15, 22, and 33. This series resistance, plus the USB driver output resistance, must be close to the USB cable's characteristic impedance of 45 (each side) to minimize transmission line reflections. The PACUSB-D1/D2/D3 is manufactured in a 5-pin SC70 or a 5-pin SOT23 package and is available with optional lead-free finishing.. * * * * * * Applications * * * * * ESD protection and termination of USB downstream ports Desktop PCs Notebooks Set-top boxes USB hubs (c)2010 SCILLC.

Note 2: ESD voltage applied to pins with respect to GND, one at a time; unused pins are left open. Note 3: 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 and 5. Note 4: 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).

Insertion Loss vs. Frequency Performance Curve, PACUSB-D3(SOT23-6) Rev. 2 | Page 6 of 10 | www.onsemi.com PACUSB-D1/D2/D3 Application Information The PACUSB-D1/D2/D3 provides a complete interface for a single downstream USB port typically found in computers and USB hubs. It integrates the series resistors (R1) and the 15k 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 PACUSB-D1/D2/D3 should be placed on the PCB between the USB controller and the USB connector, as shown on the Connection Diagram, Figure 5. Figure 5. Connection Diagram for PACUSB-D1/D2/D3 Devices To guarantee the best ESD and filtering performance, it is recommended to physically locate the PACUSBD1/D2/D3 close to the USB connector. Also, the trace lengths between the PACUSB-D1/D2/D3 and the USB controller should be kept as short as possible.
