USBQNM50405CE3 Datasheet PDF - Microsemi

●This Transient Voltage Suppressor (TVS) has a 5V standoff voltage and is assembled in a QFN143 package which

●is compatible (pin for pin) with the SOT-143 package. The configuration gives protection to 1 bi-directional data or

●interface line. It is designed for use in applications where protecon is required at the board level from voltage

●transients caused by electrostatic discharge (ESD) as defined in IEC 61000-4-2 (±30kV), electrical fast transients

●(EFT) per IEC 61000-4-4 (±8kV) and effects of secondary lightning.

●These TVS arrays have a peak power rating of 500 watts for an 8/20 ?s pulse (figure 1). This array is suitable for

●protection of sensitive circuitry consisting of TTL, CMOS, DRAMs, SRAMs, HCMOS, HSIC microprocessors,

●UNIVERSAL SERIAL BUS (USB) and I/O transceivers. The USBQNM504xxC product provides board level protection

●from static electricity and other induced voltage surges that can damage or upset sensitive circuitry. This particular

●device is aimed specifically at MRI application due to the absence of ferrous elements in the metal lead frame.
