USB Downstream Port Terminator
Product Description
The PACUSBVB-D1/D2/D3 is a single-channel USB
downstream-port termination network. It integrates
EMI/RFI
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: 15Ω, 33Ω, and 22Ω.

must be close to the USB cable’s characteristic

The PACUSBVB-D1/D2/D3 is housed in a 6-pin
SOT23 package and is available with optional lead-
free finishing.
