STPOWER MDmesh DM9 AG automotive-grade 600V/650V super-junction MOSFETs deliver high efficiency and ruggedness for on-board chargers and DC/DC converters in both hard- and soft-switching topologies.
The standout feature of the MDmesh DM9 AG series is its RDS(on) per die area coupled with a minimal gate charge. This combination leads to lower energy losses and superior switching performance, setting a new benchmark figure of merit. The latest technology in the series ensures a tighter gate-source threshold voltage (VGS(th)) spread, which sharpens the switching capabilities of the MOSFETs, resulting in lower turn-on and turn-off losses.
Moreover, these devices offer improved body-diode reverse recovery characteristics, thanks to a new optimized process that not only enhances the reverse recovery but also increases the MOSFETs' overall ruggedness. The diode's low reverse-recovery charge (Qrr) and fast recovery time (trr) position the MDmesh DM9 AG series as an ideal choice for phase-shift zero-voltage switching topologies that require the highest levels of efficiency.
The series also provides a variety of through-hole and surface-mount packages, enabling designers to achieve a compact form factor without compromising on power density and system reliability. The TO-247 LL (long-lead) package is a popular through-hole option that facilitates easy integration into existing designs, while surface-mount packages like the H2PAK-2 (2 leads) and H2PAK-7 (7 leads) are tailored for efficient bottom-side cooling when used with thermal substrates or PCBs equipped with thermal vias. Additionally, the HU3PAK and ACEPACK™ SMIT topside-cooled surface-mount packages are available for those seeking alternative cooling solutions.
The first device to be introduced in the STPOWER MDmesh DM9 AG series is the STH60N099DM9-2AG, a 27A AEC-Q101 qualified N-channel 600V device that showcases a 76mΩ typical RDS(on) in an H2PAK-2 package.
ST is committed to expanding this family to include a full range of devices, covering a broad array of current ratings and on-resistances from 23mΩ to 150mΩ, ensuring that there's a suitable component for a wide variety of automotive power applications.
