ESD protection to 15kV contact discharge per
IEC 61000-4-2 international standard
Lead-free version available
The PACUSB-U1/U2/U3 integrate EMI/RFI filter com-
ponents R1 and C1, as recommended by the USB
specification. Because these are upstream USB
devices, they are terminated with a single 1.5kΩpull-up

3.3
There are three options for the value of the series
resistor R1:
•
•
•
For PACUSB-U1, R1=15Ω
For PACUSB-U2, R1=33Ω
For PACUSB-U3, R1=22Ω
Applications
This series resistance plus the USB driver output resis-
tance must be close to the USB cable’s characteristic
impedance of 45Ω (90Ω balanced) to minimize trans-
mission line reflections.

In addition, these parts provide a very high level of pro-
tection for sensitive electronic components that may be
subjected to electrostatic discharge (ESD). The input
and output pins are designed and characterized to dis-
sipate ESD strikes of 15kV safely, a level well beyond
the maximum requirements of the IEC 61000-4-2 inter-
national standard.
Using the MIL-STD-883D (Method 3015) specification
for Human Body Model (HBM) ESD, all pins are pro-
tected for contact discharges to greater than 30kV.
The PACUSB-U1/U2/U3 is housed in either a 6-pin
SC70 or 6-pin SOT23 package and is available with
optional lead-free finishing.

Note 1: ESD applied to input/output/V3.3 pins with respect to GND, one at a time. Clamping voltage is measured at the opposite side
of the EMI filter to the ESD pin (i.e., if ESD is applied to pin 1, then clamping voltage is measured at pin 6). Unused pins are
open.
Note 2: These parameters guaranteed by design.

PACUSB-U1/U2/U3
Application Information
The PACUSB-U1/U2/U3 is targeted for upstream USB
ports (peripherals). It provides series termination, EMI
filtering, and ESD protection for the two USB data lines
D+ and D-.
Connections for Full Speed Operation
Full Speed devices have the pull-up resistor (R2) con-
nected to the D+ data line, as shown in Figure 1. Pin1
is tied to the D+ line of the USB controller. Pin 6 is con-
nected to the D+ line on the USB connector.
The USB Specification revision 1.1 provides for two
data rates:
•
The Full Speed signaling bit rate at 12 Mbits per
second, and
Connections for Low Speed Operation
Low Speed devices have the pull-up resistor (R2) con-
nected to the D- data line, as shown in Figure 2. Pin 1
is tied to the D- line of the USB controller; pin 6 is con-
nected to the D- line on the USB connector.
•
The Low Speed signaling bit rate at 1.5 Mbits per
second.
The speed is selected by connecting one of the data
lines (D+ or D-) to a 3.3V supply voltage via a 1.5kΩ
pull-up resistor (R2).
