Vishay Intertechnology’s latest 200-V FRED Pt ultrafast recovery rectifiers come in the thermally efficient FlatPAK 5×6 package with a low profile of
The rectifiers combine their low profiles with high forward current ratings of 6 A (2 x 3 A) for the VS-6DKH02-M3 and VS-6DKH02HM3 and 8 A (2 x 4 A) for the VS-8DKH02-M3 and VS-8DKH02HM3. The rectifiers’ FRED Pt technology enables ultrafast recovery times down to 25 ns, low reverse recovery charge, and soft recovery features over the entire working temperature range of –55°C to 175°C. The devices’ low forward voltage dropdown to 0.7 V reduces power losses and improves efficiency. The new rectifiers feature an MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of 260°C. RoHS-compliant and halogen-free, the devices are ideal for automated placement and allow for automated optical inspection (AOI) in automotive systems.
