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

Ω, 33Ω, and 22Ω.

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 lead-

free finishing.
