Diodes 100V PowerDI®8080 Automotive MOSFET
Diodes expands its PowerDI8080-5 MOSFET portfolio with an automotive-compliant 100V ultra-low RDS(on) device and 40V–80V options for high-power BLDC motors and DC-DC converters in ICE, electric, and hybrid vehicles.
Diodes Incorporated (Diodes) expands its PowerDI8080-5 automotive-compliant N-channel MOSFET portfolio with the introduction of an industry-leading, ultra-low RDS(ON), 100V MOSFET. Introduced alongside new 40V to 80V MOSFETs, all of the 8mm x 8mm gullwing-leaded devices are designed to minimize conduction losses, reduce heat generation, and maximize overall efficiency. Applications include brushless DC (BLDC) motors and DC-DC conversion systems in battery electric vehicles (BEVs), hybrid electric vehicles (HEVs), and internal combustion engine (ICE) platforms.
Engineers can leverage the 1.5mΩ (max.) RDS(ON) of the 100V-rated DMTH10H1M7SPGWQ in 48V BLDC motor drives used in power steering and braking systems. Other high-power applications include battery disconnect switches and on-board chargers (OBC). Designers can also choose from the 80V-rated DMTH81M2SPGWQ.
The 40V-rated DMTH4M40SPGWQ features a maximum RDS(ON) of 0.4mΩ, one of the lowest in the industry, suitable for 12V BLDC motors and DC-DC applications. The 40V-rated logic MOSFET DMTH4M40LPGWQ offers a low RDS(ON) of 0.64mΩ at a gate-source voltage (VGS) of 4.5V for low-voltage, microcontroller-driven automotive applications, such as actuators/fan controls and load switches, without sacrificing on-state losses. The 60V-rated DMTH6M70SPGWQ offers high performance for 24V applications.
The PowerDI8080-5 package has a PCB footprint of just 64mm², approximately 40% of the area occupied by the legacy TO-263 (D2PAK) package, alongside an off-board profile of 1.7mm, making it ideal for small-footprint applications. Furthermore, copper clip die bonding reduces the thermal resistance (RthJC) to as low as 0.3°C/W, which enables drain currents as high as 847A without risk of damage. The gullwing lead configuration facilitates automated optical inspection (AOI) and enhances temperature cycling reliability, supporting robust automotive manufacturing processes.
