Diodes Incorporated has expanded its automotive MOSFET portfolio with the introduction of a new 100V N-channel device in its PowerDI®8080-5 package, aimed at improving efficiency and thermal performance in next-generation 48V automotive systems.
The newly launched MOSFET, along with additional 40V to 80V variants, is designed to deliver ultra-low RDS(ON) performance, helping reduce conduction losses and heat generation in high-power automotive applications. These devices target a wide range of use cases, including brushless DC (BLDC) motor drives and DC-DC conversion systems across battery electric vehicles (BEVs), hybrid electric vehicles (HEVs), and internal combustion engine (ICE) platforms.
At the core of the lineup is the 100V-rated DMTH10H1M7SPGWQ, which offers a maximum RDS(ON) of 1.5mΩ. This makes it suitable for demanding applications such as 48V BLDC motor drives used in power steering and braking systems, as well as battery disconnect switches and on-board chargers. The portfolio also includes an 80V-rated option for similar high-power applications.
For lower voltage requirements, Diodes has introduced a 40V MOSFET with a maximum RDS(ON) of 0.4mΩ, positioning it among the lowest in its class for 12V automotive systems. A logic-level variant further supports microcontroller-driven applications such as actuators, fan controls, and load switches, maintaining efficiency even at reduced gate voltages. A 60V option is also available for 24V system designs.
The PowerDI8080-5 package features a compact 8mm x 8mm footprint, occupying approximately 40% less board space than traditional TO-263 packages. Its low-profile design, combined with copper clip bonding, reduces thermal resistance and supports high current handling capabilities—up to 847A—while maintaining reliability.
Additionally, the gullwing lead configuration enhances manufacturability by enabling automated optical inspection and improving thermal cycling performance. These features make the devices well-suited for robust automotive production environments.
