Choosing the right rectifier bridge for your application requires careful consideration of several factors:
Select a bridge with a current rating higher than your maximum required output current, accounting for derating based on operating temperature and duty cycle.
The voltage rating should be at least 20% higher than the peak AC input voltage to account for voltage spikes and ensure reliable operation.
Consider thermal management needs and board space constraints. Larger packages generally offer better thermal performance for higher power applications.
Choose between single-phase (full-wave) or three-phase (bridge) configurations based on your AC input requirements.

Compare SolutionsSingle-phase rectifier bridges contain 4 diodes arranged to convert single-phase AC to DC. Three-phase rectifier bridges contain 6 diodes arranged to convert three-phase AC to DC. Single-phase bridges are used in most consumer applications, while three-phase bridges are used in industrial and high-power applications.
Select a bridge with a voltage rating that is at least 20% higher than the peak AC input voltage (Vpeak = Vrms × 1.414). For example, if your AC input is 230Vrms, the peak voltage is about 325V, so select a bridge rated for at least 400V.
Key parameters include voltage rating (VRRM), average forward current (IF(AV)), forward voltage drop (VF), thermal resistance (Rth), and package type. The specific requirements will depend on your application's power level and thermal management constraints.
