Miniature automotive MOSFETs

Diodes Incorporated has introduced the 40V-rated DMTH4008LFDFWQ and 60V-rated DMTH6016LFDFWQ automotive-compliant MOSFETs packaged in DFN2020.

These miniature MOSFETs occupy just 10% of the PCB area of larger packages, such as SOT223, enabling greater power density in DC-DC converters, LED backlighting, ADAS, and other ‘under-the-hood’ automotive applications.

The DMTH4008LFDFWQ has a typical RDS(ON) of 11.5mΩ at VGS = 10V and a gate charge, Qg, of just 14.2nC. The DMTH6016LFDFWQ has a typical RDS(ON) of 13.8mΩ at VGS = 10V and a Qg of 15.2nC. Similarly, both devices are qualified to 175°C and packaged in the sidewall plated DFN2020, making them suitable for use in high ambient temperature environments.

When used in a typical application, such as a 12V, 5A buck converter, the DMTH4008LFDFWQ dissipates 20% less power than other comparable MOSFETs. This is a significant improvement in efficiency and provides automotive designers with greater flexibility and the freedom to increase power density in new or existing automotive applications.

The DMTH4008LFDFWQ and DMTH6016LFDFWQ are automotive-compliant to AEC-Q101 and supported by PPAP for full traceability.
