While the STR-Z2062 is a legacy component, its design philosophy contributed to the modern emphasis on energy efficiency. The component utilizes MOSFET technology, which is characterized by high input impedance and low on-resistance. This allows for fast switching speeds with minimal power loss as heat. In an era preceding modern energy standards like Energy Star, components like the STR-Z2062 were quietly driving down the energy consumption of household appliances. By ensuring that power supplies operated at higher efficiency rates—often exceeding 80% compared to the 50-60% of older linear supplies—these ICs played a small but cumulative role in reducing global electricity demand.
