1.5KE9.1A - TVS Diodes

Download the 1.5KE9.1A datasheet PDF. This datasheet also covers the 1.5KE variant, as both devices belong to the same tvs diodes family and are provided as variant models within a single manufacturer datasheet.

General Description

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

Key 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).
