The 1.5KE Series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

Features:

  • 1500W peak pulse capability at 10/1000μs waveform, repetition rate (duty cycles):0.01%
  • Glass passivated chip junction in DO-201 Package
  • Fast response time: typically less than 1.0ps from 0 Volts to BV min
  • Excellent clamping capability
  • Typical failure mode is short from over-specified voltage or current
  • Whisker test is conducted based on JEDEC JESD201A per its table 4a and 4c
  • IEC-61000-4-2 ESD 30kV(Air), 30kV (Contact)
  • ESD protection of data lines in accordance with IEC 61000-4-2
  • EFT protection of data lines in accordance with IEC 61000-4-4
  • Low incremental surge resistance
  • Typical IR less than 1μA when VBR min>12V
  • High temperature to reflow soldering guaranteed: 260°C/40sec / 0.375”,(9.5mm) lead length, 5 lbs., (2.3kg) tension
  • VBR @ TJ = VBR@25°C x (1+αT x (TJ - 25)) (αT:Temperature Coefficient, typical value is 0.1%)
  • Plastic package is flammability rated V-0 per Underwriters Laboratories
  • Matte tin lead–free plated
  • Halogen free and RoHS compliant
  • Pb-free E3 means 2nd level interconnect is Pb-free and the terminal finish material is tin(Sn) (IPC/JEDEC J-STD- 609A.01)

Applications:

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.
