TS1821LEX

TS1821LEX 1-Line, Bi-directional, TVS Protection Features Applications  IEC61000-4-2 (ESD) +/-30kV (air), +/-30KV(contact)  IEC61000-4-4 (EFT) 80A (5/50 ns)  IEC61000-4-5 (Surge) the PeakPulseCurrent(@tp=8/20us) is 12A Protects one I/O line (bidirectional)  Working voltages : 18V  Low leakage current  Cell Phone Handsets and Accessories    Microprocessor based equipment   Portable Instrumentation   Serial and Parallel Ports. Personal Digital Assistants (PDA’s) Notebooks, Desktops, and Servers Networking and Telecom Peripherals Mechanical Characteristics Description The TS1821LEX is designed for applications  SOD323 package   Flammability Rating: UL 94V-0   High temperature soldering guaranted:260°C /10s Packaging: Tape and Reel Reel size: 7 inch Circuit Diagram requiring transient overvoltage protection I/O_1 capability. They are intended for use in voltage and ESD sensitive equipment such as computers, printers, business machines , communication systems , medical equipment and other applications. These devices are ideal for situations where board space is at a premium. This series has been specifically designed to protect sensitive components which are connected I/O_2 to power data and transmission lines from overvoltage caused by ESD(electrostatic discharge), Pin Configuration CDE (Cable Discharge Events ) , and EFT (electrical fast transients). 2 1 SOD323 (Top View) Revision D1 1 　ｓｅｒｖｉｃｅ＠ｊｙ－ｅｌｅｃｔｒｏｎｉｃｓ．ｃｏｍ．ｃｎ 　ｗｗｗ．ｊｙ－ｅｌｅｃｔｒｏｎｉｃｓ．ｃｏｍ．ｃｎ TS1821LEX 1-Line, Bi-directional, TVS Protection Absolute Maximum Rating Symbol Parameter Value Units VESD ESD per IEC 61000-4-2 (Air) ESD per IEC 61000-4-2 (Contact) ±30 ±30 kV IPP Peak Pulse Current(8/20us) 12 A TOPT Operating Temperature -55/+150 °C TSTG Storage Temperature -55/+150 °C 260 (10 sec.) °C TL Lead Soldering Temperature Electrical Characteristics (T = 25C) Symbol Parameter VRWM Nominal Reverse Working Voltage IR Reverse Leakage Current @ VRWM VBR Reverse Breakdown Voltage @ IT IT Test Current for Reverse Breakdown VC Clamping Voltage @ IPP IPP Maximum Peak Pulse Current CESD VR IPP IT IR VC VBR VRWM I IR IT VRWM VBR VC V Parasitic Capacitance Reverse Voltage f Small Signal Frequency IF Forward Current VF Forward Voltage @ IF Symbol IPP Bi-Directional TVS Test Condition Minimum Typical VRWM IR VRWM =18.0V, T = 25C 0.01 Maximum Units 18 V 0.1 uA 22 V VBR IT = 1mA VC IPP = 8A, tp = 8/20μs 34 V VC IPP = 12A, tp = 8/20μs 36 V 28 pF CESD Revision D1 20 VR = 0V, f = 1MHz 25 2 　ｓｅｒｖｉｃｅ＠ｊｙ－ｅｌｅｃｔｒｏｎｉｃｓ．ｃｏｍ．ｃｎ 　ｗｗｗ．ｊｙ－ｅｌｅｃｔｒｏｎｉｃｓ．ｃｏｍ．ｃｎ TS1821LEX 1-Line, Bi-directional, TVS Protection Package Outline  SOD323 package Package Outline Dimensions Revision D1 3 　ｓｅｒｖｉｃｅ＠ｊｙ－ｅｌｅｃｔｒｏｎｉｃｓ．ｃｏｍ．ｃｎ 　ｗｗｗ．ｊｙ－ｅｌｅｃｔｒｏｎｉｃｓ．ｃｏｍ．ｃｎ TS1821LEX 1-Line, Bi-directional, TVS Protection Tape and Reel Specification Revision D1 4 　ｓｅｒｖｉｃｅ＠ｊｙ－ｅｌｅｃｔｒｏｎｉｃｓ．ｃｏｍ．ｃｎ 　ｗｗｗ．ｊｙ－ｅｌｅｃｔｒｏｎｉｃｓ．ｃｏｍ．ｃｎ TS1821LEX 1-Line, Bi-directional, TVS Protection Marking Codes 4G Ordering Information Part Number TS1821LEX Working Voltage Quantity Per Reel Reel Size 18V 3,000 7 Inch Note: (1)“4G”is part number,fixed (2) no cathode line and date code Revision D1 5 　ｓｅｒｖｉｃｅ＠ｊｙ－ｅｌｅｃｔｒｏｎｉｃｓ．ｃｏｍ．ｃｎ 　ｗｗｗ．ｊｙ－ｅｌｅｃｔｒｏｎｉｃｓ．ｃｏｍ．ｃｎ
