UCLAMP3311PQTCT

The µClamp3311PQ transient voltage suppressor is specifically designed to protect sensitive components which are connected to low-voltage data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (cable discharge events), and EFT (electrical fast transients). It is rated to Grade 3 of AEC-Q100 for use in automotive applications.The µClamp3311PQ is constructed using ’s proprietary EPD process technology. The EPD process provides low standoff voltages with significant reductions in leakage currents and capacitance over silicon avalanche diode processes. They feature a true operating voltage of 3.3 volts for superior protection when compared to traditional pn junction devices.The µClamp3311PQ is in an 2-pin SLP1006P2 package. It measures 1.0 x 0.6 x 0.5mm. The leads are spaced at a pitch of 0.65mm and are finished with lead-free NiPdAu. Each device will protect one line operating at 3.3 volts. It gives the designer the flexibility to protect single lines in applications where arrays are not practical. They may be used to meet the ESD immunity requirements of IEC 61000-4-2. The combination of low voltage, small size and high ESD surge capability makes them ideal for protection of sensitive electronics in automotive applications.
