USBQ50403e3 – USBQ50424e3

Compliant

500 W, Unidirectional

Low Capacitance TVS Array

DESCRIPTION

This Transient Voltage Suppressor (TVS) is assembled in a QFN-143 package which has the

same pinout and footprint as the SOT-143 package. The configuration gives protection to 1

unidirectional data or interface line. It is designed for use in applications where low

capacitance protection is required at the board level from voltage transients caused by

electrostatic discharge (ESD) as defined in IEC 61000-4-2, electrical fast transients (EFT) per

IEC 61000-4-4 and the secondary effects of lightning. These TVS arrays have a peak power

rating of 500 watts for an 8/20 μs pulse (figure 1). With a capacitance of only 3 pF, this part

can provide protection to very fast data lines including USB at 900 Mbits/sec.

V(BR)

Temperature Coefficient of Breakdown Voltage: The change in breakdown voltage divided by the change in

temperature that caused it expressed in %/°C or mV/°C.

Breakdown Current: The current used for measuring Breakdown Voltage V

PP

Peak Impulse Current: The maximum rated random recurring peak impulse current or nonrepetitive peak impulse

current that may be applied to a device. A random recurring or nonrepetitive transient current is usually due to an

external cause, and it is assumed that its effect will have completely disappeared before the next transient arrives.

V

(BR)

Breakdown Voltage: The voltage across the device at a specified current I

(BR)

in the breakdown region.

C

Clamping Voltage: The voltage across the device in a region of low differential resistance during the application of an

impulse current (I

) for a specified waveform.

WM

Working Standoff Voltage: The maximum-rated value of dc or repetitive peak positive cathode-to-anode voltage that

may be continuously applied over the standard operating temperature.
