Global discrete power transistor market this year begins to come back after sharp decline in 2012. It is expected revenue of worldwide power transistor market will grow by 7%, reaching $13.2 billion, according to market researcher IC Insights. In fact, by 2017, the annual growth rate will arrive at 8.5%, the researcher says.
There is survey showing most
power device manufacturers in 2013 saw shipments increase over last year. And this momentum is expected to maintain to the fourth quarter of this year; even experiences temporary tight supply situation, due to continued heavy volume and some external factors.
Tight supply
Recently, buyers find it hard to purchase power devices. As for factors, Hu Fengpin, power management and diversified marketing manager in Infineon Technologies (China) Co. says “Countries around the world are increasingly developing new energy sources, cloud storage and 4G communication technology for greater energy efficiency; so demand for power semiconductor climbs, resulting in tight supply situation of some models in short term.”
In addition, recently Renesas’ announcement of fading out of PC-related MOSFET market also caused some models of power devices presents tight supply, longer delivery time and price rise of some models.
Li Jingyao, Marketing Associate of APEC (Advanced Power Electronics Corp) notes Renesas has higher market shares in Taiwan with monthly shipments of about 50 to 60 million. In terms of the exit of PC market, the largest gainer would be Taiwanese manufacturers.
Higher requirements
The robust market development poses higher requirements for suppliers’ capacity and product reliability. As such, some manufacturers delicate to using large-size silicon chip. Via higher-end ultra-dense cell design, they enables chip more compact and of ultra-low impedance to increase capacity of power devices.
For instance, Infineon’s power MOSFET based on 12-inch silicon chip has started volume delivery. Hu said “Adopting large-size silicon chip in power devices production can largely improve production capacity and product consistency.”
Actively expanding different-voltage product and enhancing supply capacity for various applications is also important for lots of power devices manufacturers.
