Vishay Intertechnology's FRED Pt rectifiers in SMPC package increase power density and efficiency



FRED Pt Hyperfast and Ultrafast recovery rectifiers

Vishay Intertechnology introduced 27 new 4 A to 10 A FRED Pt Hyperfast and Ultrafast recovery rectifiers in the compact, low-profile SMPC (TO-277A) eSMP® series package. Combining extremely fast and soft recovery characteristics with low leakage current and low forward voltage drop, the AEC-Q101-qualified rectifiers reduce switching losses and over-dissipation in automotive and telecom applications.

The Vishay Semiconductors FRED Pt rectifiers released today offer reverse voltages of 100 V, 200 V, and 600 V; reverse recovery time down to 24 ns; and typical forward voltage drop down to 0.72 V in single- and dual-die configurations. With a compact footprint and low profile, the devices' SMPC (TO-277A) package saves significant PCB space compared with DPAK packages while increasing power density to lower overall costs.

Specified for output and snubber operation, the FRED Pt rectifiers are optimized for DC/DC converters and power factor correction (PFC) in automotive engine control units (ECUs), antilock braking systems (ABS), and LED lighting, in addition to telecom DC/DC bricks. The devices feature a planar structure and platinum-doped lifetime control to guarantee high overall performance, ruggedness, and reliability characteristics in these applications. The components offer an operating junction temperature to +175 °C for a more robust design.

The devices provide an MSL moisture level of 1 per J-STD-020, LF maximum peak of +260 °C, meet the JESD 201 class 2 whisker test, and are RoHS-compliant and halogen-free. The rectifiers are ideal for automated placement and allow for automated optical inspection (AOI) in automotive systems.

Samples and production quantities of the new FRED Pt rectifiers are available now, with lead times of eight to 12 weeks for larger orders. Pricing for U.S. delivery only starts at $0.16 per piece for 4 A.
