1A and 2A Schottkys with 0.65mm Profile and 0.36Vf

Vishay Intertechnology, Inc. today expanded its offering of surface-mount TMBS® Trench MOS Barrier Schottky rectifiers with 10 new 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 industry’s first 2A 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 2.5mm by 1.3mm with a low 0.65mm profile, the package is 35% thinner than the SOD123W while occupying 45% less board space. For excellent 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 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. 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. Pricing for U.S. delivery begins at $0.04 per piece for 1 A devices and $0.05 per piece for 2 A devices.
