1SMCxxA Series - 1500 Watt SMC Transient Voltage Suppressor, Unidirectional

1SMCxxA
Roll Over to Zoom

This series will be End of Life (EOL) on December 31, 2017 and is not recommended for new designs. Replacement will be the SMCJ series.

The SMC series is designed to protect voltage sensitive components from high voltage, high energy transients. They have excellent clamping capability, high surge capability, low zener impedance and fast response time.The SMC series is supplied in Littelfuse's exclusive, cost-effective, highly reliable package and is ideally suited for use in communication systems, automotive, numerical controls, process controls, medical equipment, business machines, power supplies and many other industrial/consumer applications.

Features:

  • Standard Zener Breakdown Voltage Range - 6.8 to 91 V
  • Stand-off Voltage Range - 5 to 78 V
  • Peak Power - 1500 Watts @ 1 ms
  • Maximum Clamp Voltage @ Peak Pulse Current
  • Low Leakage < 5 µA Above 10 V
  • UL Recognition
  • Maximum Temperature Coefficient Specified
  • Available in Tape and Reel
  • Response Time Typically < 1 ns
  • CASE: Void-free, transfer-molded, thermosetting plastic
  • FINISH: All external surfaces are corrosion resistant and leads are readily solderable
  • POLARITY: Cathode indicated by molded polarity notch. When operated in zener mode, will be positive with respect to anode
  • MOUNTING POSITION: Any
  • LEADS: Modified L-Bend providing more contact area to bond pads
  • MAXIMUM CASE TEMPERATURE FOR SOLDERING PURPOSES: 260°C for 10 seconds
  • WAFER FAB LOCATION: Phoenix, Arizona
  • ASSEMBLY/TEST LOCATION: Seremban, Malaysia
  • Pb-Free Packages are Available
  • SZ Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements
