Key Features

  • Radiation-hardened design qualified for space and hi-rel environments
  • 60 V / 40 A capability with only 24 mΩ Rds(on) for efficient power switching
  • 954 mJ avalanche energy rating for robust unclamped inductive switching
  • Built-in body diode for synchronous rectification without external components
  • Fast switching with 470 pF Crss for high-frequency power conversion

Applications

The STRH100N6HYG is designed for satellite power conditioning units, spacecraft DC-DC converters, and hi-rel motor controllers that must survive total ionizing dose radiation. Its 60 V breakdown and 40 A continuous drain current cover regulated bus switching and brushless motor drives in space platforms. Ground-based nuclear instrumentation and high-altitude avionics also benefit from its radiation-tolerant MOSFET design.

Frequently Asked Questions

What avalanche energy can the STRH100N6HYG withstand during unclamped inductive switching?

The STRH100N6HYG is rated for a single-pulse avalanche energy (Eas) of 954 mJ, giving it exceptional ruggedness against inductive load transients in radiation-hardened DC-DC converters and space-grade motor drive applications operating up to 60 V.

How does STRH100N6HYG's on-resistance affect efficiency in a satellite 28 V bus converter?

With a maximum Rds(on) of 24 mΩ at 40 A, the STRH100N6HYG dissipates approximately 38 mW per amp of conduction loss on a 28 V satellite bus, enabling high conversion efficiency in space power regulation where thermal management is critical.

Which radiation environments is the STRH100N6HYG qualified for?

The STRH100N6HYG is a rad-hard MOSFET qualified for total ionizing dose environments encountered in low-earth orbit and beyond. Its TO-254AA package and 60 V / 40 A ratings make it a direct choice for ESA- and NASA-grade power management in satellite and spacecraft power buses.

Can the STRH100N6HYG replace a standard 60 V MOSFET in a motor controller for aerospace use?

Yes, the STRH100N6HYG is a plug-in radiation-tolerant alternative to commercial 60 V N-channel MOSFETs, adding hi-rel qualification while maintaining 40 A continuous drain current and 24 mΩ Rds(on). Its fast-switching characteristic and built-in diode reduce external component count in the aerospace motor drive bridge.
