1.5KE350CA General Description

The 1.5KE TVS series is designed to protect sensitive equipment against electrostatic discharges according to IEC 61000-4-2, MIL STD 883 Method 3015, and electrical overstress such as IEC 61000-4-4 and 5. They are used for surges below 1500 W 10/1000 μs.This planar technology makes it compatible with high-end equipment and SMPS where low leakage current and high junction temperature are required to provide reliability and stability over time.


  • Peak pulse power:
    • 1500 W (10/1000 μs)
    • up to 10 kW (8/20 μs)
  • Stand-off voltage range from 5 V to 376 V
  • Unidirectional and bidirectional types
  • Operating Tj max: 175 °C
  • High power capability at Tj max.: up to 1100 W (10/1000 µs)
  • Lead finishing: matte tin plating


  • TVS devices are ideal for the protection of I/O interfaces, VCC bus and other vulnerable circuits used in telecom, computer, industrial and consumer electronic applications.
