PACUSB-D1

• A low-capacitance USB downstream port terminator, EMI filter, and transient over-voltage (ESD) protector in a single surface-mounted package
• 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 save board space and lower manufacturing costs compared to discrete solutions
• Capacitors matched to a precision exceeding the USB specification
• Pin-compatible with ST Microelectronics USBDFxxW5 USB Downstream Port Terminator
• Lead-free versions available

The PACUSB-D1 is a single-channel USB downstream-port termination network. PACUSB-D1 integrates EMI/RFI filter components R1 and C1,as recommended by the USB specification as well as the required 15kohm pull-down resistors(R2) to GND. In addtion, PACUSB-D1 proovides a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge(ESD). PACUSB-D1 pins will safety disspate ESD strikes of ±15kV, exceeding the maximum requirements of the STD-883D specification for human body model(HBM)ESD,all pins are protected from contact discharges to ±20kV.

PACUSB-D1 has many unique features: The first one is a low-capacitance USB downstream port terminator, EMI filter,and transient over-voltage(ESD) protector in a single surface-mounted package.The second one is compact SOT23-5 and SC70-5 package options save board space and lower manufacturing costs compared to dicrete solutions,etc.There are some absolute maximum ratings about it. Storage temperature range is -65 to 150.Power dissipation per resistor is 100 MW. Voltage on any pin(DC) is 6 V.
