PTVSHC3N24VUH

PTVSHC3N24VUH Transient Voltage Suppressor Description The PTVSHC3N24VUH Transient Voltage Suppressor is designed to replace Pin3 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 desirable 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 PTVSHC3N24VUH protects sensitive semiconductor components from damage or upset due to electrostatic discharge (ESD) and other voltage induced transient events. The PTVSHC3N24VUH is available in a DFN2× Pin1 2-3L package with working voltages of 24 volt. It is used to meet the ESD Pin2 Pin configuration immunity requirements of IEC 61000-4-2. Feature  5500W Peak pulse power per line (tP = 8/20μs)  DFN2×2-3L package  Response time is typically < 1 ns  Protect one I/O or power line  RoHS compliant  Transient protection for data lines to Pin3 Pin 1, 2 Circuit Diagram IEC61000-4-2(ESD) ±30KV(air), ±30KV(contact); IEC 61000-4-4 (EFT) 80A (5/50ns), IEC 61000-4-5 (Lightning) 140A (8/20us) Applications  Cell phone handsets and accessories  Personal digital assistants (PDA’s)  Notebooks, desktops, and servers  Portable instrumentation  Cordless phones  Digital cameras  Peripherals  MP3 players H24 004 004 004 Marking (Top View) Mechanical Characteristics  Lead finish:100% matte Sn(Tin)  Mounting position: Any  Qualified max reflow temperature:260℃  Pure tin plating: 7 ~ 17 um Rev.06.0 1 www.prisemi.com Transient Voltage Suppressor PTVSHC3N24VUH Electronics Parameter I IF Symbol Parameter VRWM Peak Reverse Working Voltage IR Reverse Leakage Current @ V RWM VBR Breakdown Voltage @ I T IT Test Current I PP Maximum Reverse Peak Pulse Current VC Clamping Voltage @ IPP PPP Peak Pulse Power CJ Junction Capacitance IF Forward Current VF Forward Voltage @ I F 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.
