PTVSHC3N12VU

PTVSHC3N12VU Transient Voltage Suppressor Description The PTVSHC3N12VU ESD protector is designed to replace multilayer varistors (MLVs) in portable applications such as cell phones, notebook computers, and PDA’s. They feature 1、2 large cross-sectional area junctions for conducting high transient currents, offer desirable 3 electrical characteristics for board level protection, such as fast response time, lower operating voltage, lower clamping voltage and no device degradation when compared to MLVs. The PTVSHC3N12VU protects sensitive semiconductor components from damage 1 or upset due to electrostatic discharge (ESD) and other voltage induced transient events. 3 2 Top View The PTVSHC3N12VU is available in a DFN2×2-3L package with working voltages of 12 volt. It is used to meet the ESD immunity requirements of IEC 61000-4-2 (±30kV air, ±30kV contact discharge) Feature Applications  5000W Peak pulse power per line (tP = 8/20μs)  Cell phone handsets and accessories  DFN2×2-3L 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 IEC 61000-4-2(ESD)  Peripherals ±30KV(air), ±30KV(contact); IEC 61000-4-4 (EFT) 80A (5/50ns), MP3 players IEC 61000-4-5 (Lightning) 200A (8/20us) 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 Rev.06.11 1 www.prisemi.com Transient Voltage Suppressor PTVSHC3N12VU Electronics Parameter I IF 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 V VC VBR VRWM IR VF IT IPP Electrical characteristics per line@25℃( unless otherwise specified) Parameter Symbol Conditions Min.

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.
