SMF-Packaged 30 V / 40V / 100V Schottkys rated to 2A


New Products Apr 07, 2016 by Jeff Shepard

Vishay Intertechnology, Inc. today introduced six new surface-mount Schottky barrier rectifiers in the low-profile DO-219AB (SMF) package. Providing space-saving alternatives to SMA and SOD123W packages, the Vishay Semiconductors SS1FL3, SS2FL3, SS1FL4, SS2FL4, SS1FH10, and SS2FH10 provide reverse voltages of 30V, 40V, and 100V and offer high current ratings up to 2A for automotive and commercial applications, and industrial applications such as freewheeling diodes for inductive loads like relays, valves, and transformers.

With a typical height of 0.98 mm, the rectifiers' SMF package is 46% lower than the conventional SMA package — reducing weight by 23% and saving 49% more PCB space — and 2% lower than the SOD123W package while sharing the same footprint size. The SMF (flat lead) provides improved thermal resistance of 21 degrees C/W from junction to lead, compared with the conventional SMA (J-lead) package with thermal resistance of 28 degrees C/W from junction to lead. Offering low forward voltage drops down to 0.31V at 1A, the devices reduce power loss and improve efficiency in high-frequency inverters, dc-dc converters, and freewheeling and polarity protection diodes.

All devices released today are available in AEC-Q101-qualified versions. The rectifiers feature a maximum operating junction temperature to +175 degrees C and an MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of 260 degrees C. Compliant with RoHS Directive 2011/65/EU and halogen-free according to JEDEC JS709A standards, the devices are wave- and reflow-solderable.

Samples and production quantities of the new Schottky barrier rectifiers are available now, with lead times of eight weeks for larger orders. Pricing for U.S. delivery only starts at $0.06 per piece for the SS1FL3, SS1FL4, and SS1FH10 and at $0.08 per piece for the SS2FL3, SS2FL4, and SS2FH10.
