Transcription

1 110CAT3G Series, SZ110CAT3G Series 400 Watt Peak Power Zener Transient Voltage Suppressors Bidirectional The series is designed to protect voltage sensitive components from high voltage, high energy transients. They have excellent clamping capability, high surge capability, low zener impedance and fast response time. The series is supplied in the Littelfuse exclusive, cost-effective, highly reliable package and is ideally suited for use in communication systems, automotive, numerical controls, process controls, medical equipment, business machines, power supplies and many other industrial/consumer applications. Features Working Peak Reverse Voltage Range 10 V to 78 V Standard Zener Breakdown Voltage Range 11.7 V to 91.3 V Peak Power ms ESD Rating of Class 3 (> 16 kv) per Human Body Model Response Time is Typically < 1 ns Flat Handling Surface for Accurate Placement Package Design for Top Slide or Bottom Circuit Board Mounting Low Profile Package SZ Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC Q101 Qualified and PPAP Capable These are Pb Free Devices Mechanical Characteristics: CASE: Void-free, transfer-molded plastic FINISH: All external surfaces are corrosion resistant and leads are readily solderable MAXIMUM CASE TEMPERATURE FOR SOLDERING PURPOSES: 260 C for 10 Seconds POLARITY: Cathode polarity notch does not indicate polarity MOUNTING POSITION: Any PLASTIC SURFACE MOUNT ZENER OVERVOLTAGE TRANSIENT SUPPRESSORS V V R 400 W PEAK POWER CASE 403D PLASTIC MARKING DIAGRAM xxc = Device Code (Refer to page 3) A = Assembly Location Y = Year WW = Work Week = Pb Free Package ORDERING INFORMATION Device ** Package Shipping 1xxCAT3G 5,000 / (Pb Free) Tape & Reel SZ1xxCAT3G Littelfuse.com xxc AYWW (Pb Free) 5,000 / Tape & Reel **The T3 suffix refers to a 13 inch reel.
