- Micro Clamp TM Description
The µClamp TM series of TVS arrays are designed to protect sensitive electronics from damage or latch-up due to ESD. They are designed for use in applications where board space is at a premium. Each device requires less than 2.9mm2 of PCB area and will protect up to four lines. They are unidirectional devices and may be used on lines with positive signal polarities. The µclamp TM3304A 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 silicon-avalanche diode processes. They feature a true operating voltage of 3.3 volts for superior protection when pared to traditional pn junction devices. These devices may be used to meet the immunity requirements of IEC 61000-4-2, level 4. They offer desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device degradation. The small SC89 package makes them ideal for use in portable electronics such as cell phones, PDAs, notebook puters, and digital cameras. u Clamp3304A
