25milli ohms on-resistance complementary MOSFET pair for DC motor control apps

Diodes Incorporated has announced the DMC4040SSD complementary dual MOSFET for use in low voltage, single- and three-phase brushless DC (BLDC) motor control applications. The DMC4040SSD features matched N-channel and P-channel Rds (on) performance of 25milli ohms at a Vgs of 10V to ensure DC losses in motor loads are balanced and minimized.

The enhancement mode MOSFET pair is rated with a Vds of 40V, making them suitable for 24V DC motor systems controlling cooling and extractor fans, pumps, compressors and printer heads.

The DMC4040SSD has a continuous current rating of 6A and a pulsed current rating of 29A, enabling motor torque currents of up to five times the continuous current to be supported during motor start up or stalled motor conditions.

Packaged in the industry-standard SO-8 package, the DMC4040SSD device will also bring PCB space-saving advantages over single MOSFET package alternatives.

To create a complete high-efficiency BLDC motor control solution, the DMC4040SSD MOSFET package can also be deployed in conjunction with Diodes' own range of ZXBM102x single-phase and ZXBM200x two-phase pre-driver 2 motor controllers and companion Hall sensors.
