PRODUCT DESCRIPTION

format product datasheet

The PACUSB-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 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.

There are three options for the value of the series resistor R1: 15Ω, 22Ω, and 33Ω. This series resistance, plus the USB driver output resistance, must be close to the USB cable's characteristic impedance of 45Ω (each side) to minimize transmission line reflections.

The PACUSB-D1/D2/D3 is manufacured in a 5-pin SC70 or a 5-pin SOT23 package and is available with optional lead-free finishing.

Note: Some of the devices listed here have suggested replacements available. Please see additional information at the end of this page.
