Power transistors are designed to handle higher current and voltage levels (e.g., up to 100A/1000V) and dissipate more heat, whereas regular transistors are for low-power signal applications (e.g., <1A).
Consider voltage and current ratings based on load requirements, switching frequency, thermal management needs (heat sinking), and package type for installation compatibility.
