ON Semiconductor: low-loss IGBTs suitable for solar-power inverters

ON Semiconductor has launched a new family of IGBTs employing trench/field-stop technology, to provide a new option for power systems switching at up to 50kHz and requiring high efficiency.

The new Field Stop III family offers improved conduction and switching characteristics as well as a superior freewheeling diode. Use of Field Stop III IGBTs provides for a reduction in power losses of up to 30% compared to the previous generation of Field Stop IGBTs. The first IGBTs in the family are the NGTBxxN120FL3WG and NGTBxxN120L3WG.

Featuring excellent switching characteristics and reduced conduction losses at high currents, these rugged devices are well suited to industrial applications.

Users of the new Field Stop III family benefit from ON Semiconductor’s long track record of quality and reliability in IGBTs.

ON Semiconductor has had automotive-qualified IGBTs in production for more than a decade.

In 2011, the company started developing new high-voltage, high-current devices for the growing industrial and consumer markets, which demand high-efficiency solutions.
