New rectifiers increase power density and efficiency

Vishay Intertechnology has expanded its portfolio of surface-mount TMBS Trench MOS Barrier Schottky rectifiers with 16 new 2A and 3A devices in the eSMP series low profile SMP (DO-220AA) package. The rectifiers provide a wide range of reverse voltages from 45V to 200V, while their 3A rating is claimed to be the industry's highest for the SMP package to increase power density.

With their forward voltage drop down to 0.36V for 2A and 0.37V for 3A devices, the rectifiers decrease power loss and improve efficiency in high-frequency inverters, DC-DC converters, and freewheeling and polarity protection diodes for industrial and commercial applications. The devices are also offered in AEC-Q101 qualified versions for automotive applications.

The new rectifiers provide a maximum operating junction temperature up to +175C and an MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of +260C. The devices are RoHS-compliant and halogen-free.
