The surface-mount TMBS – Trench MOS Barrier Schottky – rectifier range comprises ten 1A and 2A devices in the eSMP series MicroSMP (DO-219AD) package. Providing space-saving alternatives to Schottky rectifiers in the SOD123W, the Vishay General Semiconductor devices feature reverse voltages from 45V to 150V and include the first 2 A TMBS rectifiers in the MicroSMP to deliver forward voltage as low as 0.40V.
Currently, Schottky rectifiers with current ratings to 2A are typically available in the SOD123W and SMA packages. The devices released today increase power density by offering this high forward current in the smaller MicroSMP. Measuring 2.5 x 1.3 mm with a low 0.65 mm profile, the package is 35% thinner than the SOD123W, while occupying 45% less board space. For thermal performance, the MicroSMP features an asymmetric leadframe design.
With their forward voltage drop down to 0.36V for 1A devices and 0.40V for 2A devices, the rectifiers reduce 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. The rectifiers feature a maximum operation junction temperature up to +175C.
