PowerDI8080-packaged MOSFET rises power density in automotive applications
Diodes Incorporated has introduced an innovative high current, thermally efficient power package that meets the needs of electric vehicle (EV) applications. The first product to be released in the PowerDI8080-5 package is the DMTH4M70SPGWQ, a 40V automotive-compliant MOSFET that features a typical RDS(ON) of just 0.54mΩ at a gate drive of 10V, while its gate charge is 117nC.
The PowerDI8080-5 package has a PCB footprint of 64mm², which is 40% less than that occupied by the TO263 (D2PAK) package format. It also has an off-board profile of 1.7mm, which is 63% lower than that of a TO263. The copper clip bonding between the die and the terminals facilitates a low junction-to-case thermal resistance of 0.36°C/W. This enables the PowerDI8080-5 to handle currents up to 460A and deliver a power density that is eight times greater than a TO263 package. With its industry-leading performance, the product enables designers of automotive high-power BLDC motor drives, DC-DC converters, and charging systems to maximize system efficiency while ensuring power dissipation is kept to an absolute minimum
The DMTH4M70SPGWQ is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. Its gull wing leads facilitate optical inspection (AOI), as well as improving temperature cycling reliability. This device is available at $4.99 in 2000 piece quantities.
