Vishay Releases Two New Schottky Rectifiers With 0.35V Forward Voltage Drops

April 15, 2009 by Jeff Shepard

Vishay Intertechnology, Inc. launched two new Schottky rectifiers with low forward voltage drops of 0.35V at + 85°C and 0.4V at + 25°C. Featuring the miniature MicroSMP power package and voltage ratings of 20V (MSS1P2U) and 30V (MSS1P3U) at 1A, the devices are said to provide high current power density and low thermal resistance to enable space-saving designs.

The MicroSMP package of the MSS1P2U and MSS1P3U measures only 2.7 by 1.4mm, with a 0.68mm profile. Combined with the devices’ high current density of 1 A, the rectifiers are designed to provide more power in a smaller space for snubbers in hard disk drives for notebook computers, LCD TVs, and desktop TVs; secondary rectifiers for miniature switchmode power supplies and adaptors and for power-supply-type battery chargers; polarity protection for handheld equipment, such as PMPs, digital cameras, MP3 players, navigation systems, GPS, and cell phones; and polarity protection of power lines and signal lines in automotive and industrial systems.

The MSS1P2U and MSS1P3U feature a peak forward surge current of 30A and maximum junction temperature of + 125°C. Well suited for automated placement, the rectifiers meet MSL level 1, per J-STD-020, LF maximum peak of + 260 °C. The devices are RoHS complaint in accordance with 2002/95/EC and WEEE 2002/96/EC, and they are halogen-free according to IEC 61249-2-21.

Samples and production quantities of the MSS1P2U and MSS1P3U rectifiers are available now, with lead times of eight weeks for larger orders. Pricing for U.S. delivery is $0.04 per piece in 10,000-unit quantities, $0.03 per piece in quantities from 10,000 to 99,000, and $0.025 per piece in quantities of 100,000 or more.
