USBQNM50415CE3/TR7

This Transient Voltage Suppressor (TVS) is assembled in a non-magnetic QFN-143 package with a leadframe 100% free of iron. It has the same pinout and footprint as the SOT-143 package and is aimed at applications in MRI machines and other magnetic environments where the use of ferrous metals is not acceptable. The configuration gives protection to 1 bi-directional 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. With a capacitance of only 3 pF, this part can provide protection to very fast data lines including USB at 900 Mbits/sec.
