iDEAL Semiconductor Unveils SuperQ™ MOSFET with Industry-Leading Short-Circuit Robustness for 72V+ Battery Systems

New 150V/2.5mΩ device delivers industry-leading short-circuit robustness and enables up to 50% component reduction in 72V+ battery management systems

 iDEAL Semiconductor, a leader in high-performance power silicon,  announced the availability of its SuperQ™ MOSFET technology, purpose-built to solve the critical safety and efficiency trade-off in high-voltage (72V and higher) battery management systems (BMS). The new platform sets an industry benchmark for short-circuit withstand capability (SCWC), the most vital safety metric for the BMS discharge switch.

The proliferation of high-voltage battery packs in e-mobility, drones and professional power tools introduces a high-stakes challenge: protecting against catastrophic failure during external short-circuit events, where currents can spike into the thousands of amps. The discharge MOSFET is the single component responsible for isolating the battery pack under these extreme conditions.

"In high-energy packs, robustness is non-negotiable. Traditional MOSFET designs are forced to compromise between achieving ultra-low R_DS(on) for efficiency and the structural integrity needed to survive a massive short-circuit current," said Dr. Phil Rutter VP of Design at iDEAL Semiconductor. "The SuperQ™ platform eliminates this compromise. Our proprietary cell structure delivers the market's lowest on-resistance alongside a safety margin that is simply unmatched, giving designers the confidence to build smaller, more reliable, and lower-cost battery systems."

1.4x Superior Short-Circuit Withstand Current

iDEAL Semiconductor's internal testing demonstrated SuperQ's significant performance advantage. A head-to-head comparison of the iS15M2R5S1T (150V, 2.5mΩ, TOLL package) against a leading competitor revealed:

The SuperQ device exhibited a 1.4 times higher short-circuit failure capability than its closest competitor. This breakthrough performance is achieved through a proprietary cell structure featuring a wider conduction region that maximizes power density and structural integrity under extreme stress.

Lower System Cost and Enhanced Reliability

For battery pack designers, this superior SCWC translates directly into system-level benefits:

• Component Reduction: Because each SuperQ device handles a significantly higher short-circuit current, designers can use up to 50% fewer MOSFETs in parallel to meet the same safety requirements.
  
  
• Cost Savings: Reducing the component count and complexity leads to a substantial decrease in the total Bill of Materials (BOM) and simplifies board layout.
  
  
• Efficiency: Maintaining ultra-low R_DS(on) of 2.5mΩ minimizes conduction losses, extending battery run-time and reducing thermal management needs.

The SuperQ portfolio is available immediately with devices up to 200V, providing solutions for battery platforms ranging from 72V to over 144V.
