PTVSHC1DF24VB Transient Voltage Suppressor Description The PTVSHC1DF24VB 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 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 PTVSHC1DF24VB protects sensitive semiconductor components from damage or upset due to electrostatic discharge (ESD) and other voltage induced transient events. The PTVSHC1DF24VB is available in a SOD-123FL package with working voltages of 24 volt. It is used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (±15kV air, ±8kV contact discharge) Feature Applications ? ? 3500W Peak pulse power per line (tP = 8/20μs) Cell phone handsets and accessories ? SOD-123FL 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 ?
