USBQ50405CE3/TR7

USBQ50403Ce3 – USBQ50424Ce3 HALOGEN 500 W, Bidirectional Low Capacitance TVS Array Available FREE 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 bidirectional 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 610004-4 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.

PART NOMENCLATURE USB Q 5 04 03 C e3 USB Suitable RoHS Compliant QFN-143 Package Bidirectional Designator 500 W P PP Rating Rated Standoff Voltage (V WM ) (see Electrical Characteristics table) 4 Pin Package SYMBOLS & DEFINITIONS Definition Symbol α V(BR) I (BR) ID I PP V (BR) VC V WM 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 (BR). Standby Current: The current through the device at rated stand-off voltage. 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. Breakdown Voltage: The voltage across the device at a specified current I (BR) in the breakdown region. Clamping Voltage: The voltage across the device in a region of low differential resistance during the application of an impulse current (I PP ) for a specified waveform. 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.
