TVS Diode Arrays

Upstream USB Port Terminator with ESD Suppression & EMI Filtering

SPUSB1 Series

The Littelfuse SPUSB1 Series is a multifunctional USB port protection

network designed to provide ESD protection, EMI/RFI filtering and line

termination for a single USB 1.1 port. The SPUSB1 can replace a mini-

mum of ten typically larger “discrete” devices resulting in inventory and

placement cost savings.

The SPUSB1 Series combines Transient Voltage Suppression (TVS)

avalanche diodes, EMI/RFI filtering components (R1 and C1), and

a1.5kΩ termination resistor (R2). The filtering components are included

to satisfy recommendations in the USB 1.1 specification, and the 1.5kΩ

resistor (R2) is included as a pull-up resistor to VBUS.

The SPUSB1 Series can be used for termination and protection

of“upstream” USB devices such as PDAs, digital cameras, scanners and

hubs which are often at risk from transient voltage surges and

electromagnetic interference from both internal and external sources.

To support a wide range of circuit conditions, Littelfuse offers three

resistance values for the series resistor (R1). The series resistance plus

the USB driver output resistance must be close to the USB cable’s char-

acteristic impedance of 45Ω (90Ω balanced) to minimize transmission

line reflections.

Features

• One upstream USB port terminator, EMI filter and transient

overvoltage protector in a single surface-mount package

• Compact SC70 package saves board space and lowers

manufacturing costs compared to discrete solutions
