Since the semiconductor recession in 2009 and the strong year of recovery in 2010, sales of power transistors have been affected by market volatility, declining in three of the last five years due to inventory corrections and reductions in System manufacturers concerned with economic weakness and price erosion in some product categories. After recovering from a 7% drop in 2015, sales of energy transistors grew 5% in 2016 to the US $ 12.9 billion and are expected to reach a record high this year, with global revenues growing 6% to the US $ 13,600 million. The expected 2017 growth in sales of power transistors will be the first consecutive annual increase in this semiconductor market segment in six years, and that will push dollar volumes beyond the record high of $ 13.5 billion set in 2011, IC Insights said. In 2012 and 2013, energy transistors suffered their first consecutive annual sales decline in more than three decades – 8% and 6%, respectively – after rising 12% in 2011 and a 44% increase in recovery 2010 compared to the 2009 year of recession. 

The power transistor market then recovered in 2014 with a sharp increase of 14%, only to fall 7% in 2015. In 2016, this category of discrete semiconductor market began to stabilize and is expected to continue expanding at a pace modest in the coming years, IC Insights indicated. But nevertheless, Volatility in the first half of this decade resulted in an unusual drop in the size of the power transistors market over the past five years, IC Insights noted. Between 2011 and 2016, sales of power transistors fell by a compound annual growth rate of 0.9% negative, compared to a 25-year average annual increase of 6.4% (between 1991 and 2016). IC Insights predicted that global sales of energy transistors will increase by a CAGR of 4.2% between 2016 and 2021, reaching the US $ 15.8 billion in the last year of the forecast. compared to a historical average annual increase of 25 years of 6.4% (between 1991 and 2016).
