iDEAL Semiconductor has expanded its SuperQ line with new 200 V MOSFETs that deliver low on-resistance in popular power packages. The lineup includes the iS20M5R5S1T in a compact TOLL package and the iS20M6R3S1P in a TO-220 package, providing options for both surface-mount and through-hole designs.
The iS20M5R5S1T offers a maximum RDS(on) of 5.5 mΩ, allowing higher power density and lower conduction losses in space-constrained boards. The iS20M6R3S1P delivers a maximum RDS(on) of 6.3 mΩ in the TO-220 package, ideal for applications needing mechanical mounting or direct heatsinking. Together, they give designers flexible packaging choices without sacrificing efficiency in high-current circuits.
These MOSFETs are targeted at motor-drive applications where efficiency, thermal performance, and reliability are critical. They support industrial temperatures up to 175 °C and handle high currents, rated at roughly 151 A for the TOLL device and 172 A for the TO-220 version.
Additional features include short-circuit protection, a gate-threshold voltage tolerance of ±0.5 V for easier paralleling, avalanche rating, and 100 % unclamped inductive switching (UIS) testing during production to ensure robust operation under transient conditions.
Beyond motor drives, the devices can also be used in switched-mode power supplies, synchronous rectification stages on the secondary side of power converters, and other high-current industrial or battery-powered systems that require low conduction losses and reliable thermal performance.
The company plans to extend the 200 V, 5.5 mΩ SuperQ device platform to additional industry-standard packages during 2026. Planned variants include a D2PAK-7L device intended for high-current surface-mount applications with improved thermal and mechanical performance, and a TOLT version designed for compact layouts with top-side cooling.
The iS20M5R5S1T and iS20M6R3S1P devices are currently in volume production and available through global distribution channels, while the D2PAK-7L and TOLT versions are in sampling with production planned later in 2026.
