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 recom-
mended by the USB specification, as well as the
required 15k
Ω 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 resis-
tance, plus the USB driver output resistance, must be
close to the USB cable’s characteristic impedance of
45
Ω (each side) to minimize transmission line reflec-
tions.
The PACUSBVB-D1/D2/D3 is housed in a 6-pin
SOT23 package and is available with optional lead-
free finishing.
