High-performance power MOSFETs for enhanced efficiency and reliability unveiled

Littelfuse, Inc. has announced the release of the IXTN400N20X4 and IXTN500N20X4 Ultra Junction X4-Class Power MOSFETs.

The new devices expand upon the current 200V X4-Class Ultra Junction MOSFETs, providing some of the lowest on-state resistances available. Their high current ratings enable designers to replace multiple low-current-rated devices connected in parallel, streamlining the design process and improving reliability and power density in applications. Also, the screw-mounted terminals of the SOT-227B package enable rugged and stable mounting.

These new 200V MOSFETs supply the lowest on-state resistances, improving and complementing the existing the company's X4-Class Ultra Junction family portfolio. Compared to the existing state-of-the-art X4-Class MOSFET solutions, these MOSFETs offer up to 2x higher current ratings and RDS(on) values up to 63% lower.

The new MOSFETs are ideal for a range of low-voltage power applications where minimising on-state losses is essential, including BESS, Battery chargers, Battery formation, DC battery load switch, and Power supplies.

"The new devices will allow designers to replace multiple low-current rated devices, connected in parallel, with a single device solution," said Sachin Shridhar Paradkar, global product marketing engineer at Littelfuse. "This unique solution simplifies gate driver design, improves reliability, improves power density and PCB space utilisation."
