Magnachip Semiconductor Corp. has released its third- generation 200-V medium voltage (MV) mosfets for light electric vehicle (LEV) motor controllers, such as those used in e-bikes, battery management systems, and industrial power supplies. Incorporating third-generation trench mosfet technology, the three new 200-V MOSFETs deliver a 50% reduction in capacitance compared to the previous generation 100-V MV MOSFET.
In addition, “the enhanced design of the core cell and termination helps lower RDS(ON) and total gate charge to achieve a high figure of merit,” said Magnachip. The MOSFETs also offer increased energy efficiency thanks to their fast switching and high-power density.
The third-generation MOSFETs are available in three package types: a TO-leadless (TOLL), M2PAK, and TO-220. The MOSFETs feature an operating junction temperature from -55°C to 175°C and a high level of avalanche ruggedness, contributing to their suitability for LEV motor controller and industrial power supply applications.
200-V MV MOSFETs
Earlier this year, Magnachip launched a low RDS(on) MV 40-V MOSFET to control brushless direct current (BLDC) motors for automotive applications, such as electric oil pumps, engine cooling fans, electric power steering, and battery cooling fans. Magnachip said demand for high-efficiency BLDC motors for EVS are increasing and medium-Voltage MOSFETs will be essential for these motors. Developed to reduce the conduction loss of automotive BLDC motors, the 40-V MOSFET is fully AEC-Q101 (Automotive Electronics Council-Q101) certified.
