Vishay Intertechnology Launches 45 V and 50 V TMBSŪ Rectifiers in DO-221BC (SMPA) Package With Low 0.95 mm Profile

Devices Offer Low Voltage Drop to Cut Power Losses and Increase Efficiency in Automotive and Commercial Applications

MALVERN, Pa. —  Vishay Intertechnology, Inc. (NYSE: VSH) today expanded its offering of TMBSŪ Trench MOS Barrier Schottky rectifiers with seven new 45 V and 50 V devices. For automotive and commercial applications, the high current density rectifiers offer current ratings from 3 A to 8 A and low forward voltage drop in the low-profile, surface-mount DO-221BC (SMPA) package.

With their low forward voltage drop down to 0.37 V at 3 A and profile of only 0.95 mm, the rectifiers released today reduce power loss and improve efficiency in low-voltage, high-frequency DC/DC converters, switching power supplies, freewheeling diodes, and polarity protection. The three 45 V devices are AEC-Q101-qualified for automotive applications, while the four 50 V rectifiers are ideal for commercial applications, especially smartphone and tablet chargers.

The new rectifiers feature a maximum operation junction temperature of +150 °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 compliant to RoHS Directive 2011/65/EU and halogen-free according to JEDEC JS709A standards.
