The PACUSBVB-D1/D2/D3 is a single-channel USB downstream-port termination network. PACUSBVB-D3 integrates EMI/RFI filter components R1 and C1, as recommended by the USB specification as well as the required 15k pull-down resistors (R2) to GND. In addition, PACUSBVB-D1/D2/D3 provides a very high level of protection for sensitive electronic components that PACUSBVB-D3 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 PACUSBVB-D3 also features a fifth zener diode (cathode at pin 5) which provides ESD protection for the USB VBUS line.
There are three options of PACUSBVB-D3 for the value of the series resistor R1: 15, 33, and 22. This series resistance, plus the USB driver output resistance, must be close to the USB cable&primes characteristic impedance of 45 (each side) to minimize transmission line reflections.
The PACUSBVB-D1/D2/D3 PACUSBVB-D3 is housed in a 6-pin SOT23 package and is available with optional lead-free finishing.
