Key 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 W, 33 W, and 22 W. This series resistance, plus the USB driver output resistance, must be close to the USB cable’s characteristic impedance of 45 W (each side) to minimize transmission line reflections. The.

PACUSBVB USB Downstream Port Terminator with VBUS ESD Protection Product Description The PACUSBVB−D1 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 1 5 k W p u l l −d o w n r e s i s t o r s ( R 2 ) t o G N D . I n a d d i t i o n , PACUSBVB−D1 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 15 kV, 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 20 kV.
