MALVERN, Pa. — Nov. 3, 2021 — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced 10 new AEC-Q101 qualified FRED Pt^® Gen 5 600 V Hyperfast and Ultrafast rectifiers for automotive applications. Offering the best reverse recovery performance for devices in their class, the 15 A, 30 A, 60 A, and 75 A Vishay Semiconductors rectifiers are designed to increase the efficiency of AC/DC and DC/DC converters and of hard- and soft-switched or resonant designs.

The devices released today offer 30 % lower reverse recovery losses than the closest competing rectifiers and 48 % lower than previous-generation FRED Pt solutions, while maintaining low conduction and switching losses. The result is improved light- and full-load efficiency in high speed LLC output rectification stages for EV / HEV on-board chargers.

The rectifiers are available in TO-247AD and TO-220AC packages, and X-type Hyperfast and H-type Ultrafast speed classes. X-type devices offer the advantage of lower Q_RR, while H-type rectifiers feature lower forward voltage. RoHS-compliant and halogen-free, the components offer high temperature operation to +175 °C.

Device Specification Table:

¹I_F = rated current, T_J = 125 °C
²T_J = 125 °C, I_F = rated current A, V_R = 400 V, dI_F/dt = 1000 A/μs
³T_J= 25 °C I_F = 1 A dI_F/dt = 100 A/μs, V_R = 30 V

Samples and production quantities of the new FRED Pt rectifiers are available now, with lead times of 12 weeks. Pricing for U.S. delivery only starts at $0.50 per piece.
