Magnachip Semiconductor Corporation (NYSE: MX) has added 15 sixth-generation E6 super-junction MOSFETs to its power semiconductor portfolio, targeting TV switch-mode power supplies, notebook adapters, PC power supplies, and consumer and industrial power applications below 1 kW, according to a company statement.

The E6 Series includes 500 V and 600 V options. The 600 V lineup is offered in DPAK (TO-252), TO-220FA, and TO-220SFA packages across multiple on-resistance classes. The devices are now in mass production.

Magnachip tested its 600 V, 280 mΩ E6 MOSFET in a TO-220SFA package in the power factor correction stage of a TV switch-mode power supply. At a 100 Vac input under the same test conditions, the E6 MOSFET operated at approximately 5.3% lower temperature than Magnachip's previous-generation MOSFET.

"As power systems become more compact, designers need MOSFETs that help them manage heat and switching noise while meeting efficiency targets," said Hyuk Woo, Chief Technology Officer of Magnachip Semiconductor. "We developed the E6 Series around these requirements for TV and computing power applications, offering customers performance and package options suited to their operating conditions."
