The power semiconductor market was worth $10.1 billion in 2009, declining by 24% from 2008 (power modules dropped 26%, and discretes 24%). the market has not dropped by such a large extent since 2001, when it fell 22% because of the “dot com” collapse.
IMS Research estimates the discrete power semiconductor market was worth $8.1 billion in 2009. Power MOSFETs and power rectifier revenues, together accounting for 74% of the total, each declined approximately 25%. Protected MOSFETs saw the largest decline, falling by nearly 40%, though this is not surprising as over 95% are bought by the automotive sector.
Supplier rankings for the discrete power semiconductor market saw an important change in 2009; Toshiba moved from 5th place in 2008 to 1st in 2009. Josh Flood, market analyst at IMS Research, “Toshiba performed incredibly in 2009 considering the economic situation at the beginning of the year. One of the many reasons for Toshiba’s strong performance was its large customer base in Asia outside Japan, where the discrete power semiconductor market fell by only 5% to 15% depending on the device category.”
Infineon Technologies was estimated to have increased its power semiconductor market share to 11.1% in 2009 and remained the largest supplier to the market for the seventh consecutive year. The top five suppliers were estimated to account for almost 40% of the total 2009 market. IMS Research has released preliminary results for its latest report on the Power Semiconductor market.
