μClampTM 5-Line ESD protection Array PROTECTION PROTECTION PRODUCTS - MicroClampTM Description The μClampTM 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 five lines. They are bidirectional devices and may be used on lines where the signal polarities swing above and below ground. TVS diodes are solid-state devices designed specifically for transient suppression. They feature large cross-sectional area junctions for conducting high transient currents. They offer desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device degradation. These devices may be used to meet the immunity requirements of IEC 61000-4-2, level 4. The small SC89 package makes them ideal for use in portable electronics such as cell phones, PDAs, notebook computers, and digital cameras. uClamp0506A Features Transient protection for data lines to IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact) IEC 61000-4-4 (EFT) 40A (5/50ns) Protects five bidirectional I/O lines Ultra-small SC-89 package (1.7 x 1.7 x 0.6mm 0.6mm) 1.7 2 requires less than 2.9mm of PCB area Working voltage: 5V Low leakage current Low operating and clamping voltages Solid-state silicon-avalanche technology Mechanical Characteristics SC-89 (SOT-666) package RoHS / WEEE Compliant Molding compound flammability rating: UL 94V-0 Marking : Marking Code and pin 1 indicator Weight: 2.9mg (typical) Packaging : Tape and Reel per EIA 481 Applications Cellular Handsets and Accessories Cordless Phones Notebooks and Handhelds Portable Instrumentation Digital Cameras Peripherals MP3 Players Dimensions 1.70 0.50 Schematic & PIN Configuration 1.25 1.70 0.30 0.60 Maximum Dimensions (mm) Revision 03/21/07 1 SC-89 (Top View) www.semtech.com uClamp0506A PROTECTION PRODUCTS Absolute Maximum Rating R ating Peak Pulse Power (tp = 8/20μs) Maximum Peak Pulse Current ( tp = 8/20μs) ESD per IEC 61000-4-2 (Air) ESD per IEC 61000-4-2 (Contact) Lead Soldering Temperature Operating Temperature Storage Temperature Symbol Pp k Ip p V PP TL TJ TSTG Value 100 7 +/- 20 +/- 12 260 (10 sec.) -55 to +125 -55 to +150 Units Watts Amps kV °C °C °C Electrical Characteristics (T=25oC) Parameter Reverse Stand-Off Voltage Reverse Breakdown Voltage Reverse Leakage Current Reverse Leakage Current Clamp ing Voltage Clamp ing Voltage Junction Cap acitance Symbol VRWM V BR IR IR VC VC Cj It = 1mA VRWM = 5V, T=25°C VRWM = 3V, T=25°C IPP = 1A, tp = 8/20μs IPP = 7A, tp = 8/20μs Between I/O Pins and Gnd VR = 0V, f = 1MHz 30 6 7.8 0.100 0.050 Conditions Minimum Typical Maximum 5 9 1 0.500 9 12 40 Units V V μA μA V V pF © 2007 Semtech Corp. 2 www.semtech.com μClamp0506A PROTECTION PRODUCTS Typical Characteristics Non-Repetitive Peak Pulse Power vs. Pulse Time 10 Power Derating Curve 110 100 90 % of Rated Power or I PP 80 70 60 50 40 30 20 10 0 Peak Pulse Power - P PP (kW) 1 0.1 0.01 0.1 1 10 Pulse Duration - tp (μs) 100 1000 0 25 50 75 100 125 150 Ambient Temperature - TA (oC) Clamping Voltage vs. Peak Pulse Current 14 Junction Capacitance vs. Reverse Voltage 25 24 Clamping Voltage - VC (V) 12 Capacitance - Cj (pF) 23 22 21 20 19 18 10 8 Waveform Parameters: tr = 8μs td = 20μs 0 1 2 3 4 5 6 7 8 6 Peak Pulse Current - IPP (A) f = 1 MHz 0 1 2 3 Reverse Voltage - VR (V) 4 5 17 Insertion Loss S21 CH1 21 LOG S 6 dB /REF 0 dB .

The device is connected as follows: 1. Bidirectional protection of five I/O lines is achieved by connecting pins 1, 3, 4, 5, and 6 to the data lines. Pin 2 is connected to ground. The ground connection should be made directly to the ground plane for best results. The path length is kept as short as possible to reduce the effects of parasitic inductance in the board traces. 2 1 3 Circuit Diagram 4 5 6 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.
