Rutronik is adding the Optima and Speedy high-voltage FRED types with 600 V and 1200 V, respectively, from PANJIT to its product range. The power diodes improve the system efficiency of an application and are used for low-frequency (Optima) or high-frequency (Speedy) applications. They feature low leakage current and improved EMI characteristics. PANJIT FREDs are ideal for rectifier or freewheeling circuits in a wide range of power applications, such as UPS systems or data centers, but also household appliances.
Optima-type FREDs are suitable for rectifier circuits such as high-power bridge diodes and bypass diodes, optimized for lower power losses at low VF, and predestined for low switching frequency applications. Speedy-FREDs, on the other hand, are more suitable for high-frequency freewheeling switching in CCM boost PFC and Vienna PFC to achieve maximum system efficiency.
