Semtech TClamp2472S

Low Capacitance TransClamp® Surge Protection for xDSL Interfaces

Add to Watch List

TClamp®2472S is specifically designed to provide secondary surge and ESD protection for Class-H VDSL2 line drivers. TClamp2472S integrates low capacitance, surge-rated steering diodes with a high power transient voltage suppressor (TVS). The TVS utilizes snap-back or “crow-bar” technology to minimize device clamping voltage and features high surge current capability of 20A (tp=8/20us).

Features


  • Transient Protection to
    • IEC 61000-4-2 (ESD) Level 4
    • IEC 61000-4-4 (EFT) 2kV (5/50ns)
    • IEC 61000-4-5 (Lightning) 20A (8/20μs)
  • Bias diodes prevent charging of TVS capacitance
  • Working Voltage: 24V
  • Low Capacitance: 3.5pF Maximum
  • Capacitance variation <1.5pF (1V to 24V)
  • Solid-State Silicon-Avalanche Technology
  • JEDEC SOT-23 6L package
  • Pb-Free, Halogen Free, RoHS/WEEE Compliant
  • Nominal Dimensions: 1.0 x 0.60 x 0.40 mm
  • Lead Finish: matte Tin
  • Molding Compound Flammability Rating: UL 94V-0
  • Marking : Marking Code + Date Code
  • Packaging : Tape and Reel
