“Providing space-saving alternatives to Schottky rectifiers in the SOD123W, the Vishay General Semiconductor devices feature reverse voltages from 45 to 150V and include the industry’s first 2 A TMBS rectifiers in the MicroSMP to deliver forward voltage as low as 0.40V,” said the firm. “Currently, Schottky rectifiers with current ratings to 2A are typically available in the SOD123W and SMA packages.”
“For thermal performance, the MicroSMP features an asymmetric lead-frame design,” said Vishay.
Forward drop down can be as low as 0.36V for 1A devices and 0.40V for 2A devices.
They are aimed at low voltage, high frequency inverters, dc-dc converters, and free-wheeling and polarity protection diodes for commercial and industrial applications.
The devices are also available AEC-Q101 qualified version for automotive use.
Maximum operating junction temperature is 175°C and an MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of +260 °C.
The MicroSMP is 2.5 x 1.3 x 0.65mm high – the package is 35% thinner than the SOD123W while occupying 45% less board space.
