They offer superior electrical characteristics such as lower clamping voltage and no device degradation when compared to MLVs. They are designed to protect sensitive semicon- ductor components from damage or upset due to electrostatic discharge (ESD), lightning, electrical fast transients (EFT), and cable discharge events (CDE). The μClamp®2501T is constructed using Semtech’s proprietary EPD TVS process technology. The EPD process provides low operating voltages with significant reductions in leakage currents and capacitance over silicon-avalanche diode processes. They feature a true sub 5 volt operating voltage for superior protection when compared to traditional pn junction devices. The μClamp2501T is in a 2-pin SLP1006P2T package. It measures 1.0 x 0.6 x 0.4mm. 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 2.5 volts. It gives the designer the flexibility to protect single lines in applications where arrays are not practi- cal. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (±15kV air, ±8kV contact discharge). The combination of small size and high ESD surge capability makes them ideal for use in portable applications such as cellular phones, digital cameras, and MP3 players. 1 2 |
