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.
