Frequently Asked Questions
How does STRH40P10HYG's 75 mΩ on-resistance affect power dissipation at 34 A in a satellite power bus?
At the 34 A maximum drain current, the 75 mΩ RDS(on) yields a conduction loss of approximately 87 W (I² × R = 34² × 0.075). Thermal design must ensure the TO-254AA package junction temperature stays within rated limits, typically using a heat spreader or cold plate in spacecraft enclosures.
What avalanche energy can STRH40P10HYG absorb, and how does that help protect inductive loads in space power systems?
The device is rated for 1133 mJ of single-pulse avalanche energy (EAS), meaning it can safely clamp and absorb the energy stored in large inductors during turn-off events. This makes STRH40P10HYG well-suited for unsuppressed inductive loads in 100 V spacecraft power buses without needing additional external TVS protection.
Which package does STRH40P10HYG use, and does it support standard space-grade mounting practices?
STRH40P10HYG is housed in the TO-254AA vertical through-hole package (JEDEC-95 code TO-254AA), a common form factor in space and defense power modules that allows direct chassis mounting for heat sinking. The 3-lead metal package is compatible with radiation-tolerant PCB assembly processes and conformal coating.
For procurement of STRH40P10HYG in a satellite program, what lead time and lifecycle factors should buyers consider?
The YTEOL indicator for STRH40P10HYG is approximately 5 years, so programs with 10-year or longer procurement horizons should place lifetime buys or negotiate long-term agreements with STMicroelectronics authorized distributors early. Lead times for radiation-hardened devices often exceed 26 weeks, requiring advance planning in satellite production schedules.
