Replace mechanical relays in spacecraft bus platforms and payloads with rad hard, optically coupled SSRs

anchor

Overview

Infineon's IR HiRel-branded radiation hardened (rad hard) solid-state relay (SSR) portfolio includes single, dual, and octal devices in hermetically sealed packages and tested up to 100 krads(Si) total ionizing dose (TID). The family includes optically coupled, buffered and non-buffered solid-state relays processed to MIL-PRF-38534 Class K, using Infineon¡¯s industry-leading Rad Hard MOSFETs for highest reliability.

Key Features

  • TID capability of 100 krads(Si)
  • Optically coupled
  • 1000 VDC input to output isolation
  • Hermetically sealed

About

Rad hard SSR benefits and applications

The benefits of replacing mechanical switching with rad hard solid-state switching include:

  • Improved mechanical shock and vibration resistance
  • No switch cycles limitation over mission duration
  • No contact bouncing
  • Low-power logic-level control (3.3 V or 5 V)
  • Controlled rise and fall time for improved EMI performance?


Infineon's IR HiRel-branded SSRs are suitable for high-reliability applications such as:?

  • Solar array management
  • Heater controls
  • Bus switching
  • Ground power isolation
  • Generic load switching
Rad hard power solutions for space bus platforms and payloads

Infineon¡¯s rad hard power electronics are used throughout satellite bus platforms and payloads to improve size, efficiency, and power density of space power systems. Certified to ESA and DLA standards, Infineon¡¯s rad hard power management and power conversion portfolio is recognized globally for its excellent performance, reliability, longevity, and world-class design heritage.

Our design, operations, and quality systems exceed military standards. Infineon offers semiconductor-based products specifically designed for space applications where commercial electronics cannot meet the requirements.

Rad hard power solutions for space bus platforms and payloads

Infineon¡¯s rad hard MOSFETs are tested to verify their radiation hardness capability, with an assurance program based on the requirements outlined in ESCC-5000, MIL-PRF-19500, and associated slash sheets.

Our IR HiRel-branded products exceed the standard requirements with a sampling size up to two times greater than is required for every manufacturing lot.

Both pre- and post-irradiation performance are tested and specified using the same drive circuitry and test conditions to provide a direct comparison. Radiation harden-by-design techniques virtually eliminate the possibility of single-event gate rupture (SEGR) and single-event burnout (SEB) in the rad hard power MOSFETs.

Robust performance is then verified through extensive single event effects testing.

IR HiRel¡¯s decades-long space heritage

For over 75 years, IR HiRel has been a trusted partner in space exploration, providing high-reliability memory, power, and RF solutions that have enabled groundbreaking missions.

From the farthest reaches of our solar system to low Earth orbit, our technology has played a critical role in advancing our understanding of the universe.
