40 V OptiMOS™ power MOSFETs – Portfolio & applications

Optimized price-performance ratio, flexible application, stable supply, product longevity

Choose from a range of single and dual N-channel power MOSFETs for 12 V or 24 VDC bus voltages. Products for smaller power handling (single and dual N- and P-channel MOSFETs) are also offered. As the name discloses, Infineon’s series of ≤40 V OptiMOS™ power MOSFETs covers several voltage classes up to 40 V. The variety of available packages including SuperSO8, DPAK, PQFN (5x6, 3.3x3.3), and TO220 endorses design and application flexibility.

≤40 V OptiMOS™ power MOSFETs may help increase system performance and efficiency. Their use can result in reduced power losses thanks to the low RDS(on) values as well as low gate and output charges. By adhering to the highest quality standards, Infineon safeguards that those MOSFETs are reliably performing under various application conditions. Furthermore, the large-scale in-house manufacturing capacities ensure that customers can rely on stable and long-term product supply.

All those who are working on one of the following (or similar) applications are well advised to browse the provided selection guide and identify the best matching power MOSFET:

  • SMPS for server, telecom, and PC power
  • Adapters
  • Chargers
  • Battery-powered applications
  • Motor control and drives
  • Battery management systems
  • Inverters
  • Mobile applications
  • and more

Discrete Power Quad Flat No-Lead (PQFN) board mounting

Power Quad Flat No-Lead (PQFN) is a surface-mount semiconductor technology designed primarily for board-mounted power applications. It eliminates unnecessary elements of packaging that contribute to higher inductance and resistance, both thermal and electrical, so that its power capabilities exceed those of comparably sized packages. In the related application note you will find more information on device construction, design and assembly considerations, as well as on subjected mechanical tests.
