USB Downstream Port Filter & TVS

For EMI Filtering and ESD Protection

PROTECTION PRODUCTS

Features

Description

The STF201 is a combination EMI filter and line termi-

nation device with integrated TVS diodes for use on

downstream USB ports. It is constructed using a

proprietary technology that allows passive components

and TVS diodes to be integrated in the same package.

Each device will provide termination, filtering, and ESD

protection for one downstream USB port. The STF201

is an easily implemented solution for meeting the

requirements of revision 1.1 of the Universal Serial Bus

specification.

Bidirectional EMI/RFI filtering and line termination

with integrated ESD protection

ESD protection for USB power (V_BUS) and data lines

(D+ & D-) to IEC 61000-4-2 Level 4

Filtering and termination for two USB data lines

Different series resistors for impedance matching

Low TVS operating voltage (5.25V)

Low leakage current

Low capacitance

Solid-state technology

USB line termination is achieved with series 22Ω or

30Ω resistors on both the D+ and D- USB lines. These

resistors preserve signal integrity by matching the cable

impedance to that of the differential driver. The 15kΩ

pull-down resistors complete the termination circuit on

each line. They are required by the USB specification

to identify the line as a downstream connection. The

47pF capacitors are used to bypass high frequency

energy to ground and for edge rate control of the USB

signals. Finally, the STF201 contains TVS diodes for

ESD protection of both (D+ & D-) data lines and the

voltage bus (V_BUS). The TVS diodes provide effective

suppression of ESD voltages in excess of 15kV (air

discharge) and 8kV (contact discharge) per IEC 61000-

4-2, level 4.

Mechanical Characteristics

EIAJ SOT23-6L package

Molding compound flammability rating: UL 94V-0

Marking : Marking Code

Packaging : Tape and Reel per EIA 481

Applications

USB Hubs

Portable electronics

Printers

Monitors

Servers, Desktop, and Notebook computers

The small size and integrated feature of the STF201

minimizes required board space and increases system

reliability. The pin-out of the device allows easy imple-

mentation. The STF201 is suitable for use in USB

hubs, computers, peripherals, and portable devices.
