New Vishay Intertechnology TMBS Produces New Rectifiers in Compact MicroSMP Package

Vishay Intertechnology’s 1 A and 2 A Devices Feature Low 0.65 mm Profile and Forward Voltage Drop Down to 0.36 V

Vishay Intertechnology announces expansion of its surface-mount TMBS Trench MOS Barrier Schotty rectifiers rollout 10 new 1A and 2A devices in the eSMP series MicroSMP (DO-219AD) package.

Vishay Intertechnology TMBSThe new released products are compact alternatives to Schottky rectifiers in the SOD123W. The Vishay General Semiconductor devices feature reverse voltages from 45 V to 150 V and include the industry’s first 2 A TMBS rectifiers in the MicroSMP to deliver forward voltage as low as 0.40 V.

Currently, Schottky rectifiers with current ratings to 2A are barely available in the SOD123W and SMA packages.

 The new released devices will increase power density by offering this high forward current in the smaller MicroSMP.  The package is 35 % thinner than the SOD123W and covers 45 % less board space.

The new rectifiers feature a maximum operating junction temperature up to +175 °C and an MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of +260 °C.

Applications and Features

With their forward voltage drop down upto 0.36 V for 1 A devices and 0.40 V for 2 A devices, the rectifiers are capable in reducing power loss and improve efficiency in low voltage, high frequency inverters, DC/DC converters, and freewheeling and polarity protection diodes for commercial and industrial applications. The devices are also available in an AEC-Q101 qualified version for automotive applications.


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