Rectifiers save space, improve thermal performance and efficiency

Vishay Intertechnology has launched a new family of surface-mount TMBS Trench MOS Barrier Schottky rectifiers in the eSMP series SlimDPAK (TO-252AE) package. Offering lower profiles and better thermal performance than devices in the DPAK, the Vishay General Semiconductor rectifiers feature reverse voltages from 45V to 150V, low forward voltage drop, and industry-high current ratings. By combining TMBS technology with the SlimDPAK package, the 40 new Schottky rectifiers released today deliver current ratings up to 35A for single-chip configurations and 40A for dual-chip, center-tap common cathode configurations. Footprint-compatible with the DPAK package, the devices’ profile is 43% lower, enabling ultra slim industrial and consumer electronics designs. In addition, their heatsink area is 14 % larger, allowing for typical thermal resistance down to 1.5C/W. With their forward voltage drop down to 0.44V at 20A, 0.46V at 35A, and 0.49V at 40A, the rectifiers reduce power losses and improve efficiency in DC-DC converters and freewheeling and polarity protection diodes. For automotive applications, the devices are also available in an AEC-Q101 qualified version. The new rectifiers feature 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. Ideal for automated placement, the devices are RoHS-compliant and halogen-free.
