MOSFET ensures automotive thermal reliability

Diodes has added a 100-V MOSFET to its lineup of 40-V to 80-V devices, all in 8×8-mm gullwing-leaded packages for automotive systems. With a maximum on-resistance of 1.5 mΩ, the DMTH10H1M7SPGWQ is well suited for 48-V BLDC motor drives used in power steering and braking systems. Like other family members, it minimizes conduction losses, reducing heat generation and maximizing overall efficiency.

The MOSFET’s PowerDI8080-5 package occupies a footprint of just 64 mm², approximately 40% less than the legacy TO-263 (D2PAK). It also offers a slim off-board profile of 1.7 mm. Copper clip die bonding reduces thermal resistance to as low as 0.3°C/W, enabling drain currents as high as 847 A without risk of damage. The gull-wing lead configuration supports automated optical inspection and enhances temperature-cycling reliability.

AEC-Q101 qualified, the DMTH10H1M7SPGWQ is rated to +175°C for high-ambient-temperature operation. One-hundred-percent unclamped inductive switching (UIS) testing during production ensures reliable, robust end applications.

The DMTH10H1M7SPGWQ is priced at $1.71 each in quantities of 5000. Contact sales via the product page for availability and purchase details.
