Vishay has introduced four new 100 V TMBS Trench MOS barrier Schottky rectifiers with high current density from 2 A to 4 A in low-profile, surface-mount SMA and SMB packages. The devices include the VSSA310S and VSSA210 in the DO-214AC (SMA) package and the VSSB410S and VSSB310 in the DO-214AA (SMB) package. The SMA and SMB packages feature low profiles of 2,29 mm and 2,44 mm, respectively.
With low forward voltage drops down to 0,56 V typical and extended avalanche capability, the devices reduce power loss and improve efficiency in freewheeling diodes, DC-DC converters, and polarity protection in switch mode power supplies (SMPS), set-top boxes and consumer electrical appliances. The new rectifiers feature a maximum junction temperature of +150°C and a moisture sensitivity level (MSL) of 1, per J-STD-020, LF maximum peak of 260°C. Suitable for automated placement, the devices are compliant to RoHS directive 2002/95/EC and WEEE 2002/96/EC.
