Key Features
- Industry-leading RDS(on) of 0.0023 Ω at 180 A delivers ultra-low conduction losses in high-current DC-DC stages
- 1000 mJ avalanche energy rating ensures exceptional ruggedness in automotive and industrial motor drive switching
- H2PAK-3/2 power package maximizes thermal dissipation for continuous 180 A operation in demanding power modules
Applications
The STH315N10F7-2 is engineered for high-current automotive DC-DC converters, 48 V mild-hybrid power stages, and industrial servo drives where 100 V blocking voltage and ultra-low resistance at 180 A minimize system losses. Its extraordinary 1000 mJ avalanche energy makes it suitable for battery charging switches subject to voltage transients in electric vehicle powertrains. The H2PAK surface-mount package integrates directly into multi-phase power modules targeting sub-1 mΩ total conduction resistance.

Frequently Asked Questions
What makes the STH315N10F7-2 stand out in high-current DC-DC converter designs?
The STH315N10F7-2 achieves an ultra-low maximum RDS(on) of 0.0023 Ω, which at 100 A produces only 23 W of conduction loss — significantly lower than standard 100 V MOSFETs in this current class. Combined with a 180 A continuous rating, it enables high-efficiency multi-phase buck converters with fewer parallel devices compared to higher-resistance alternatives.
How does the 1000 mJ avalanche energy rating benefit motor drive reliability?
The 1000 mJ single-pulse avalanche energy (EAS) of the STH315N10F7-2 absorbs inductive kickback from motor windings with several millihenry inductance at 180 A without junction damage, providing a large safety margin beyond typical EAS ratings of 100 mJ to 300 mJ found in competing devices. This robustness reduces system-level protection circuit complexity in brushless DC and stepper motor inverters.
For a 48 V automotive mild-hybrid system, why is 100 V breakdown sufficient for the STH315N10F7-2?
A 48 V nominal bus in mild-hybrid systems reaches at most 60 V to 70 V under load dump transients, giving the 100 V rated STH315N10F7-2 a comfortable 30% to 40% margin while operating in the voltage sweet spot where RDS(on) can be minimized to 0.0023 Ω. Choosing a higher-voltage rating for this application would increase on-resistance due to the fundamental RDS(on)-BVdss tradeoff.
Which H2PAK package alternatives exist if the STH315N10F7-2 has a 26-week lead time?
STMicroelectronics offers similar ultra-low-resistance N-channel MOSFETs in TO-247 and D2PAK packages within the same 100 V, 0.002 Ω to 0.004 Ω RDS(on) class, such as the STL series, which may carry shorter 8-week to 13-week lead times from secondary distributors. Engineering evaluation with TO-247 variants is feasible since both provide 100 V, 180 A class performance with equivalent gate drive requirements.
