Demand seasonality for Power Integrations' products is influenced by various factors. The company's high-power business typically experiences a downturn in the first quarter. Additionally, the comfort appliances segment tends to see a decrease in the third quarter due to build cycles. Demand in the communications sector, particularly for cell phones, also exhibits seasonal strength in certain quarters. The semiconductor industry itself is cyclical.
