5.0SMDJxxS-HRA TVS Diode Series

Littelfuse, Inc. has announced the new 5.0SMDJxxS-HRA TVS Diode Series that is designed, manufactured, and screened to provide robust overvoltage protection, with low early failures and zero degradation over continuous surge events. This TVS diode series is developed for aircraft subsystems and protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. These TVS Diodes are available in a 5000W surface-mount DO-214AB package with a high-power density of up to 5 kW. Ideal applications of this series include aircraft subsystems, aircraft power trains, low-frequency data lines, industrial automation, and harsh environment applications.



  • Delivers a higher power rating than other high-reliability TVS diode series, resulting in a 66% increase in surge handling capability.

  • Utilizes high-reliability design and up-screening process for avionics and other demanding applications.

  • The very small JEDEC DO-214AB (SMC) package, coupled with a high-power density (5 KW), provides PC board designers with a space-saving alternative to currently available options.

  • Meets DO-160 lightning protection regulatory requirements.

  • Provides a very low clamping voltage and unlimited surge life.



  • Aerospace, avionics, and aircraft subsystems (e.g., cockpit displays, fight control, radar, etc.)

  • Aircraft power trains

  • AC or DC power line protection

  • Low-frequency data lines

  • Industrial automation, and

  • Harsh environment applications


Availability & Pricing

The 5.0SMDJxxS-HRA TVS Diode Series are available in tape and reel format in quantities of 3,000.
