uClamp0511PQ µClamp® 1-Line ESD protection PROTECTION PRODUCTS - MicroClamp® Description Features ® The µClamp 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®0511PQ is in a 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 bidirectional line operating at ±5 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, Level 4 (±15kV air, ±8kV contact discharge) and higher. 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. The uClamp0511PQ is qualified to AEC-Q100 Grade 1 for Automotive use. u Transient protection for data lines to IEC 61000-4-2 (ESD) ±30kV (air and contact) IEC 61000-4-4 (EFT) 40A (tp = 5/50ns) Cable Discharge Event (CDE) u u u u u u u Ultra-small package (1.0 x 0.6 x 0.5mm) Protects one I/O or power line Low clamping voltage Working voltage: 5V Low leakage current Solid-state silicon-avalanche technology AEC-Q100 Grade 1 Qualified Mechanical Characteristics u u u u u SLP1006P2 package Molding compound flammability rating: UL 94V-0 Packaging : Tape and Reel Lead Finish: NiPdAu Pb-Free, Halogen Free, RoHS/WEEE Compliant Applications u u u u u u u u Package Dimensions Cellular Handsets & Accessories Cordless Phones Smart Phones Notebooks & Handhelds Portable Instrumentation Digital Cameras MP3 Players Automotive Applications Schematic & Pin Configuration SLP1006P2 (Bottom View) 10/19/2012 1 www.semtech.com uClamp0511PQ PROTECTION PRODUCTS Absolute Maximum Ratings Rating Symbol Value Units Peak Pulse Power (tp = 8/20µs) Ppk 170 Watts Peak Pulse Current (tp = 8/20µs) IPP 12 A ESD per IEC 61000-4-2 (Air) ESD per IEC 61000-4-2 (Contact) VESD ± 30 ± 30 kV TJ -40 to +125 °C TSTG -55 to +150 °C Operating Temperature Storage Temperature Electrical Characteristics (T=25OC unless otherwise specified) Parameter Symbol Conditions Reverse Stand-Off Voltage VRWM Pin 1 to 2 or 2 to 1 Reverse Breakdown Voltage VBR It = 1mA Pin 1 to 2 or 2 to 1 T=-40OC to +125OC Reverse Leakage Current IR VRWM = 5V, Pin 1 to 2 or 2 to 1 Min.

The device is bidirectional and may be used on lines where the signal polarity can go above and below ground. 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: l Place the TVS near the input terminals or connectors to restrict transient coupling. l Minimize the path length between the TVS and the protected line. l Minimize all conductive loops including power and ground loops. l The ESD transient return path to ground should be kept as short as possible. l Never run critical signals near board edges. l Use ground planes whenever possible. 2012 Semtech Corp. 5 www.semtech.com uClamp0511PQ PROTECTION PRODUCTS Applications Information - Spice Model Figure 1 - uClamp0511PQ Spice Model Table 1 - µClamp0511PQ Spice Parameters 2012 Semtech Corp.
