Power Transistors
By Staff -- EDN, September 18, 2008
Reflecting high demand in computer and industrial power supplies, the market for power transistors in 2007 grew 5.8%. Power transistor revenue, particularly MOSFETs, grew well (11%) in switching power supplies and direct current to direct current (DC-DC) converters in computers and communications switching stations. The industrial and medical sectors, users of insulated-gate bipolar transistor (IGBT) motor drives, grew power transistor revenue 12% in 2007. And the consumer sector, particularly appliances, remained strong users of bipolar power devices, with power transistor revenues increasing 4%. For power transistors it's helpful to look at companies by product end-use: Military, automotive, and computers.
Military: International Rectifier was the largest player in power transistors for military applications, though its growth here was flat from 2006 to 2007.
Automotive: Infineon posted a 47.9% gain in power transistors for this market followed by Fuji Electric, (ranked fifth), which grew 22.0%. Mitsubishi (with a 3.7% revenue gain) was ranked second, International Rectifier (with a 4.4% revenue gain) was ranked third in automotive applications and Vishay (with a 12.4% revenue gain) was ranked fourth.
Computers: Its strength in computers kept Fairchild Semiconductor as the top power transistor supplier.
