FRED Pt® Rectifiers

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 Semiconductor's FRED Pt rectifiers offer reverse voltages of 100 V and 200 V, reverse recovery time down to 25 ns, and typical forward voltage drop of 0.74 V for the 2 A and 0.72 V for the 3 A devices. With a compact footprint and low profile of <1 mm, the SlimSMA saves significant PCB space compared to standard SMA, SMB, and SMC packages, while increasing power density to lower overall costs.

The FRED Pt rectifiers are optimized for DC/DC converters in automotive engine control units (ECU), anti-lock 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.
