Vishay Intertechnology offers its TMBS rectifiers to improve thermal performance and efficiency and offers 20, 35, and 40A devices with a low, 1.3mm profile and forward voltage drop down to 0.44V.

The family of surface-mount TMBS Trench MOS Barrier Schottky rectifiers in the eSMP series SlimDPAK (TO-252AE) package offer lower profiles and better thermal performance than devices in the DPAK (TO-252AA), says Vishay Intertechnology. The Vishay General Semiconductor rectifiers feature reverse voltages from 45 to 150V, low forward voltage drop, and industry-high current ratings.

By combining TMBS technology with the SlimDPAK package, the 40 Schottky rectifiers deliver current ratings up to 35A for single-chip configurations and 40A for dual-chip, centre-tap common cathode configurations. Footprint-compatible with the DPAK package, the devices’ profile is 43 per cent lower, enabling slim, industrial and consumer electronics designs, points out Vishay Intertechnology. In addition, the heatsink area is 14 per cent larger, allowing for typical thermal resistance down to 1.5 degree C/W.

With a 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 TMBS Trench MOS Barrier Schottky rectifiers are also available in an AEC-Q101 qualified version.

The rectifiers have a maximum operating junction temperature up to +175 degree C and an MSL moisture sensitivity level of one, per J-STD-020, LF maximum peak of +260 degree C. Ideal for automated placement, the devices are RoHS-compliant and halogen-free.

Samples and production quantities of the new TMBS rectifiers are available now, with lead times of 12 weeks for larger orders.

Vishay Intertechnology manufactures discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors). These components are used in virtually all types of electronic devices and equipment, in the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies, and medical markets.
