www.DataSheet4U.com PulseGuard ® Suppressors Polymeric ESD Suppressors NEW Pb PGB1 Series Lead-Free 0603 Surface Mount ESD Suppressor Product Overview PulseGuard ESD Suppressors help protect sensitive electronic equipment against electrostatic discharge (ESD). They supplement the on-chip protection of integrated circuitry and are best suited for lowvoltage, high-speed applications where low capacitance is important. Data ports utilizing such high-speed protocols as USB 2.0, IEEE1394, HDMI and DVI can benefit from this new technology. PulseGuard suppressors use polymer composite materials to suppress fast-rising ESD transients (as specified in IEC 61000-4-2 and MIL-STD-883C), while adding virtually no capacitance to the circuit. 4 PULSEGUARD® SUPPRESSORS Reference Dimensions: Sn 1.60 (.063") 0.076 (.003") MIN 1.04 (.041") REF 0.787 (.031") 0.254 (.010") MIN 0.356 (.014") Features • Lead-Free • Ultra-low capacitance • Low leakage current • Fast response time • Single line of protection • Bi-directional • Withstands multiple ESD strikes • Standard EIA SOCM-1608 package • Compatible with pick-and-place processes • Available in 1,000 and 5,000 piece reels (EIA-RS481) Typical Applications • • • • • • • HDTV Hardware Laptop/Desktop Computers Network Hardware Computer Peripherals Digital Cameras External Storage Set-Top Boxes Reflow Solder 0.508 (.020") Wave Solder 0.762 (.030") 3.05 (1.20") 1.27 (.050") 1.27 (.050") 3.30 (1.30") Ordering Information 0.762 (.030") CATALOG NUMBER PGB1010603MR PGB1010603NR PIECES PER REEL 1,000 5,000 1 Equivalent Circuit 0.762 (.030") 2 Design Consideration Because of the fast rise-time of the ESD transient, placement of PulseGuard suppressors is a key design consideration. To achieve optimal ESD suppression, the devices should be placed on the circuit board as close to the source of the ESD transient as possible. Install PulseGuard suppressors directly behind the connector so that they are the first board-level circuit component encountered by the ESD transient. They are connected from signal/data line to ground. 197 w w w. l i t t e l f u s e . c o m www.DataSheet4U.com PulseGuard ® Suppressors Polymeric ESD Suppressors Pb PGB1 Series Lead-Free 0603 Surface Mount ESD Suppressor Capacitance vs. Frequency Electrical Characteristics ESD Capability IEC 61000-4-2 Direct Discharge ....................................................8kV IEC 61000-4-2 Air Discharge .......................................................15kV Clamping Voltage1 ..................................................................150V, typical Rated Voltage ........................................................................24VDC, max Capacitance2 ................................................................................0.055 pF Response Time1 ...............................................................................< 1 ns Leakage Current...............................................................................< 1nA ESD Pulse Withstand............................................1,000 pulses, minimum NOTES: 1. 8 kV direct discharge method, per IEC 61000-4-2. 2.
