STMicroelectronics: STW21N150K5 - N-Channel 1500 V, MDmesh™ K5 Power MOSFET

World’s first 1500 V super-junction MOSFETs. ST has extended its portfolio of super-junction MDmesh™ K5 MOSFETs with the introduction of the industry’s first 1500 V device. They provide the lowest RDS(on) per area and lowest gate charge (down to 47 nC), resulting in the industry’s best figure of merit (FoM). The higher breakdown voltage ensures a higher safety margin for more robust and reliable applications. They are ideal for wide input voltage range auxiliary power supplies in high-power applications such as solar inverters, factory automation, industrial drives and welding.
