PTVSHC3D7VUH--EOS浪涌防护器件.pdf

PTVSHC3D7VUH TVS Protector Description The PTVSHC3D7VUH TVS 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 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 PTVSHC3D7VUH protects sensitive semiconductor components from damage or upset due to electrostatic discharge (ESD) and other voltage induced transient events. The PTVSHC3D7VUH is available in a SOD-323 package with working voltages of 7 volt. It is used to meet the ESD immunity requirements of IEC 61000-4-2, (±30kV air, ±30kV contact discharge) Feature Applications ? 2000W Peak pulse power per line (tP = 8/20μs) ? Cell phone handsets and accessories ? SOD-323 package ? Personal digital assistants (PDA’s) ? Response time is typically 1 ns ? Notebooks, desktops, and servers ? Protect one I/O or power line ?
