PTVSHC2EN12VUT

PTVSHC2EN12VUT Transient Voltage Suppressor Description The PTVSHC2EN12VUT ESD protector is designed to replace multilayer varistors (MLVs) in portable applications such as cell phones, notebook computers, and PDA’s. They feature large cross-sectional area junctions for conducting high transient currents, offer Pin 2 Pin 1 desirable electrical characteristics for board level protection, such as fast response time, Circuit Diagram lower operating voltage, lower clamping voltage and no device degradation when compared to MLVs. The PTVSHC2EN12VUT protects sensitive semiconductor components from damage or upset due to electrostatic discharge (ESD) and other voltage induced transient events. The PTVSHC2EN12VUT is available in a DFN1610-2L package with working voltages of 12 volt. It is used to meet the ESD immunity requirements of IEC Pin 1 61000-4-2, (±30kV air, ±30kV contact discharge) H12T Pin 2 Marking (Top View) Feature Applications  3000W Peak pulse power per line (tP = 8/20μs)  Cell phone handsets and accessories  DFN1610-2L package  Personal digital assistants (PDA’s)  Response time is typically < 1 ns  Notebooks, desktops, and servers  Protect one I/O or power line  Portable instrumentation  Low clamping Voltage  Cordless phones  RoHS compliant  Digital cameras  Transient protection for data lines to  Peripherals IEC 61000-4-2(ESD) ±30KV(air), ±30KV(contact);  MP3 players IEC 61000-4-4 (EFT) 40A (5/50ns) Mechanical Characteristics  Lead finish:100% matte Sn(Tin)  Mounting position: Any  Qualified max reflow temperature:260℃  Pure tin plating: 7 ~ 17 um  Pin flatness:≤3mil  Device meets MSL1 requirements Rev.06.3 1 www.prisemi.com Transient Voltage Suppressor PTVSHC2EN12VUT Electronics Parameter Symbol Parameter VRWM Peak Reverse Working Voltage IR Reverse Leakage Current @ VRWM VBR Breakdown Voltage @ IT IT Test Current IPP Maximum Reverse Peak Pulse Current VC Clamping Voltage @ IPP PPP Peak Pulse Power CJ Junction Capacitance IF Forward Current VF Forward Voltage @ IF I IF V VC VBR VRWM IR VF IT IPP Electrical characteristics per line@25℃( unless otherwise specified) Parameter Symbol Peak Reverse Working Voltage VRWM Breakdown Voltage VBR It =1mA Reverse Leakage Current IR VRWM =12V Clamping Voltage VC Junction Capacitance Cj Conditions Min.

PCB Design For TVS diodes a low-ohmic and low-inductive path to chassis earth is absolutely mandatory in order to achieve good ESD protection. Novices in the area of ESD protection should take following suggestions to heart:  Do not use stubs, but place the cathode of the TVS diode directly on the signal trace.  Do not make false economies and save copper for the ground connection.  Place via holes to ground as close as possible to the anode of the TVS diode.  Use as many via holes as possible for the ground connection.  Keep the length of via holes in mind! The longer the more inductance they will have.
