Diodes Incorporated has announced the PowerDI 8080-5, 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 PowerDI 8080-5 package is the DIODES DMTH4M70SPGWQ, a 40 V automotive-compliant MOSFET that features a typical Rds(on) of just 0.54 milliohm at a gate drive of 10 V, while its gate charge is 117 nC. This industry-leading performance 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 PowerDI 8080-5 package has a PCB footprint of 64 square millimeters, which is 40% less than that occupied by the TO263 (D2PAK) package format. It also has an off-board profile of 1.7 mm, 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 PowerDI 8080-5 to handle currents up to 460 A and delivers a power density that is eight times greater than a TO263 package.
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 improve temperature cycling reliability. This device is available at $4.99 in 2000-piece quantities.
