Description
General part information
USBQNM50403-e3 Series
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
