PACUSBVB
USB Downstream Port
Terminator with VBUS ESD
Protection
Product Description
The PACUSBVBD1 is a singlechannel USB downstreamport
termination network. It integrates EMI/RFI filter components R1 and
C1 as recommended by the USB specification, as well as the required
15 kW pulldown resistors (R2) to GND. In addition,
PACUSBVBD1 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 15 kV,
exceeding the maximum requirements of the IEC 6100042
international standard. Using the MILSTD883D (Method 3015)
specification for Human Body Model (HBM) ESD, all pins are
protected from contact discharges to 20 kV.
The PACUSBVBD1 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 W,
33 W, and 22 W. This series resistance, plus the USB driver output
resistance, must be close to the USB cable’s characteristic impedance
of 45 W (each side) to minimize transmission line reflections.
The PACUSBVBD1 is housed in a 6pin SOT23 package and is
available with optional leadfree finishing.
