MALVERN, PA — Vishay Intertechnology (NYSE: VSH) has expanded its portfolio of 1,200-volt power semiconductors with six new hyperfast rectifiers aimed at electric vehicle, industrial automation and energy infrastructure applications, targeting growing demand for more efficient power conversion systems.
The company introduced the devices as part of its seventh-generation FRED Pt Hyperfast rectifier platform, extending its presence in markets ranging from electric transportation to renewable energy and industrial electrification.
The launch includes six rectifiers rated from 1 amp to 3 amps, including three automotive-qualified devices certified to the AEC-Q101 reliability standard for vehicle applications.
According to Vishay, the components are designed to reduce switching losses through a combination of low reverse recovery charge, low forward voltage drop and fast recovery times.
The devices are housed in the company’s eSMP SMPC HV package, a compact format intended to reduce component counts and lower bill-of-material costs in high-voltage system designs.
Specifications include recovery times of 50 nanoseconds, reverse recovery charge as low as 105 nanocoulombs, forward voltage drop down to 1.45 volts and junction capacitance as low as 7.25 picofarads.
Vishay expects the rectifiers to serve as clamp, snubber and freewheeling diodes in power supply circuits, while also providing protection functions for systems using insulated-gate bipolar transistors and silicon carbide power semiconductors.
Target markets include on-board chargers and motor systems for electric vehicles, industrial drives and tools, renewable energy generation and storage equipment, and industrial lighting applications.
The devices can operate at temperatures up to 175 degrees Celsius and withstand non-repetitive surge currents of up to 70 amps, according to the company.
Vishay noted that the rectifiers incorporate a planar semiconductor structure and platinum-doped lifetime control technology intended to improve reliability while maintaining switching performance.
The product expansion comes as manufacturers across automotive, industrial and energy sectors seek components capable of improving power efficiency, reducing thermal losses and supporting increasingly high-voltage electrical architectures.
