Vishay Intertechnology Releases New 1 A, 2 A, and 3 A Gen 7 1200 V FRED Pt Hyperfast Rectifiers in SMPC HV Package

Reducing Switching Losses and Increasing Efficiency, Devices Combine Low Q_rr Down to 105 nC and V_F Down to 1.45 V With Low Junction Capacitance, Fast Recovery Time, and Minimum Creepage Distance of 5.4 mm.

Vishay Intertechnology, Inc. expands its Gen 7 platform of 1200 V FRED Pt Hyperfast rectifiers with six new devices in the eSMP series SMPC HV package. Optimized for industrial, automotive, and energy applications, the 1 A, 2 A, and 3 A rectifiers not only offer the best trade-off between reverse recovery charge (Q_rr) and forward voltage drop for devices in their class, but also provide the lowest junction capacitance and recovery time.

The Vishay Semiconductors rectifiers release include the VS-E7SX0112-M3V, VS-E7SX0212-M3V, and VS-E7SX0312-M3V, and AEC-Q101 qualified VS-E7SX0112HM3V, VS-E7SX0212HM3V, and VS-E7SX0312HM3V. To reduce switching losses and increase efficiency, the devices combine a fast recovery time of 50 ns with Q_rr down to 105 nC typical, forward voltage drop down to 1.45 V, and junction capacitance down to 7.25 pF. The robust rectifiers offer non-repetitive peak surge current up to 70 A in a compact package measuring 4.3 mm x 6.5 mm with a low 1.1 mm profile, which is footprint-compatible with the TO-277A. Combined with a minimum 5.4 mm creepage distance and molding compound with a comparative tracking index (CTI) ≥ 600 (Material Group I), the devices reduce component counts and lower BOM costs based on IEC 60664-1 requirements for high voltage applications.

The VS-E7SX0112-M3V, VS-E7SX0212-M3V, VS-E7SX0312-M3V, VS-E7SX0112HM3V, VS-E7SX0212HM3V, and VS-E7SX0312HM3V will serve as clamp, snubber, and freewheeling diodes in flyback auxiliary power supplies and high-frequency rectifiers for bootstrap driver functionality, while providing desaturation protection for the latest fast-switching IGBTs and high-voltage Si / SiC MOSFETs. Typical applications for the devices include industrial drives and tools, on-board chargers and motors for electric vehicles (EV), energy generation and storage systems, and Ćuk converters and industrial LED SEPIC circuitry.

The rectifiers feature a planar structure and platinum-doped lifetime control that guarantee system reliability and robustness without compromising on performance, while their optimized stored charge and low recovery current minimize switching losses and reduce power dissipation. RoHS-compliant and halogen-free, the devices feature a Moisture Sensitivity Level of 1 in accordance with J-STD-020 and offer high temperature operation to +175 °C.
