MagnaChip Semiconductor of Korea has announced eight 700V and 800V series high-voltage Super Junction Metal Oxide Semiconductor Field Effect Transistors (SJ MOSFETs), optimised for TV, LED lighting and fast charger applications.

MagnaChip began SJ MOSFET development in 2013. Cumulative shipments have now reached 1.5 billion units, and the company is now launching new generations of high-voltage SJ MOSFETs.

The 800V SJ MOSFETs are designed for indoor LED lighting, fast charger devices and other industrial applications that have high or unstable input voltages.

They feature an embedded zener diode between gate and source in order to avoid damage from an external surge or electro-static discharge, thereby improving robustness and reliability.

MagnaChip has reduced the total gate charge by 30% to previous versions, which improves power efficiency and reduces switching loss.
