iDEAL Semiconductor has introduced its SuperQ™ MOSFET technology, specifically engineered to address safety and efficiency challenges in high-voltage (72V and above) battery management systems (BMS). The platform sets a new industry benchmark for short-circuit withstand capability (SCWC), a critical metric for battery discharge switches.

The rising deployment of high-voltage battery systems in applications such as e-mobility, drones, and industrial power tools demands enhanced safety mechanisms against extreme short-circuit events. The discharge MOSFET plays a vital role in isolating battery packs under such high-stress conditions.

According to Dr. Phil Rutter, Vice President of Design at iDEAL Semiconductor, “Traditional MOSFETs require trade-offs between achieving low RDS(on) for efficiency and maintaining structural integrity to withstand high short-circuit currents. SuperQ™ eliminates this compromise through a proprietary cell structure that delivers both industry-low on-resistance and unmatched safety margins.”

In internal testing, the SuperQ™ iS15M2R5S1T (150V, 2.5mΩ, TOLL package) demonstrated a short-circuit withstand capability of 800A—1.4 times greater than a comparable 150V, 2.5mΩ device from a leading competitor, which withstood 580A. This performance is achieved through a wider conduction region that maximizes power density and structural resilience under extreme conditions.

The enhanced SCWC of the SuperQ™ platform enables multiple system-level advantages:

  • Reduction in component count by up to 50% due to higher current handling capability
  • Lower total system cost from simplified layouts and reduced material usage
  • Improved efficiency through ultra-low 2.5mΩ RDS(on), decreasing power losses and thermal demands

The SuperQ™ product line is immediately available in voltage ratings up to 200V, supporting battery platforms from 72V to over 144V.
