TO-LL无引线及SMD 散热效率高封装,适合高电源需求应用
The additional Kelvin-source lead on the package also helps designers achieve higher efficiency through reduced turn-on/turn-off switching losses.
Another key characteristic is the 2.7 mm creepage between the drain and source pads, which ensures better isolation and protection from failures caused by voltage events that exceed the breakdown rating of the device.
ST offers MDmesh M6 (600V) and MDmesh DM6 (600-650V) superjunction MOSFETs in TO-LL packages targeting servers, telecom data centers, SMPS, and solar microinverters. The range of devices in TO-LL packages will be expanded with the inclusion of the latest MDmesh M9 and DM9 series of STPOWER MOSFETs. applications.
