Super Junction MOSFETs operate at 700V/800V for TVs and fast chargers
Eight 700V and 800V series high voltage super junction metal oxide semiconductor field effect transistors (SJ MOSFETs) have been announced by MagnaChip Semiconductor. The high performance devices have efficiency optimised for TVs, LED lighting and fast charger applications.
Following their introduction in 2013, SJ MOSFETs have been shipped to, among others, the world’s largest TV brands in Korea. MagnaChip has now launched the next generation 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 electrostatic discharge (ESD). The total gate charge has been reduced by 30 per cent, compared to previous versions, to improve power efficiency and reduce switching loss.
YJ Kim, CEO of MagnaChip, said: “These new product families will allow us to broaden our application coverage in consumer and industrial market segments”.
MagnaChip Semiconductor is a designer and manufacturer of analogue and mixed-signal semiconductors for communications, IoT, consumer, industrial and automotive applications.
