PACUSB-D1/D2/D3  
USB Downstream Port Terminator  
Features  
Product Description  
A low-capacitance USB downstream port termina-  
The PACUSB-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 15kΩ pull-down resistors (R2) to GND. In  
addition, PACUSB-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.

ESD protection to +20kV contact discharge, per  
MIL-STD-883D, Method 3015  
ESD protection to +15kV contact discharge, per  
IEC 61000-4-2 International Standard  
Compact SOT23-5 and SC70-5 package options

compared to discrete solutions

Lead-free versions available  
There are three options for the value of the series  
resistor R1: 15Ω, 22Ω, and 33Ω. This series resis-  
tance, plus the USB driver output resistance, must be  
close to the USB cable’s characteristic impedance of  
45Ω (each side) to minimize transmission line reflec-  
tions.  
Applications  
ESD protection and termination of USB  
downstream ports  
Desktop PCs  
Notebooks  
Set-top boxes  
The PACUSB-D1/D2/D3 is manufactured in a 5-pin  
SC70 or a 5-pin SOT23 package and is available with  
optional lead-free finishing.
