The FRED Pt rectifiers released today offer designers a choice of current ratings, packages, and speeds to optimize efficiency in their applications. With forward currents up to 3 A in the SMA package, 4 A in the SMB package, and 5 A in the SMC package, the devices increase power density to facilitate lower system costs. U Speed Ultrafast rectifiers offer the advantage of lower forward voltage while H Speed Hyperfast devices provide a lower reverse recovery charge.
The FRED Pt rectifiers are intended for power factor correction (PFC) diodes, boost diodes for discontinuous conduction mode (DCM) and critical conduction mode (CRM), and freewheeling diodes in power switching applications. The devices feature a planar structure and platinum doped lifetime control to guarantee high overall performance, ruggedness, and reliability characteristics. The components offer an operating junction temperature to +175 °C for a more robust design.
The devices offer an MSL moisture level of 1 per J-STD-020, LF maximum peak of +260 °C, and they are RoHS-compliant and halogen-free.
