PROTECTION PRODUCTS - MicroClamp® Description The µClamp®3311PQ 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 µClamp®3311PQ is constructed using Semtech’s proprietary EPD process technology. The EPD process provides low standoff voltages with significant reductions in leakage currents and capacitance over siliconavalanche diode processes. They feature a true operating voltage of 3.3 volts for superior protection when compared to traditional pn junction devices.
