1 - MicroClamp Description The uclamp series of TVS arrays are designed to protect sensitive electronics from damage or latch-up due to ESD. They are designed to replace multilayer varistors (MLVs) in portable applications. They feature large crosssectional area junctions for conducting high transient currents and offer superior electrical characteristics such as lower clamping voltage and no device degradation when compared to MLVs. They offer desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device degradation. The µclamp 511P is in a 2-pin, SLP16P2 package. It measures 1. x.6 x.5mm. The leads are spaced at a pitch of.65mm and are fi nished with lead-free NiPdAu. Each device will protect one bidirectional line operating at ±5 volts. It gives the designer the fl exibility to protect single lines in applications where arrays are not practical. They may be used to meet the ESD immunity requirements of IEC , 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.

4 Applications Information Device Connection Options These TVS diodes are designed to protect one data, I/O, or power supply line. The device is bidirectional and may be used on lines where the signal polarity can go above abd below ground. Equivalent Circuit Diagram Circuit Board Layout Recommendations for Suppression of ESD. Good circuit board layout is critical for the suppression of ESD induced transients. The following guidelines are recommended: Place the TVS near the input terminals or connectors to restrict transient coupling. Minimize the path length between the TVS and the protected line. Minimize all conductive loops including power and ground loops. The ESD transient return path to ground should be kept as short as possible. Never run critical signals near board edges. Use ground planes whenever possible. 214 Semtech Corporation 4
