TMBS rectifiers in low profile SMP package increase power density and efficiency
Vishay expands its offering of TMBS rectifiers with 16 new 2 A and 3 A devices in the eSMP series low profile SMP (DO-220AA) package. The Vishay General Semiconductor rectifiers offer low forward voltage drop down to 0.36 V to reduce power losses and increase efficiency, while their 3 A rating is the industry's highest for the SMP package.
FRED Pt ultrafast rectifiers in SMP and MicroSMP packages increase power density, improve efficiency
New 100 V and 200 V FRED Pt ultrafast recovery rectifiers increase power density by providing the high current ratings typically reserved for the SMA package — up to 2 A — in the smaller eSMP series SMP (DO-220AA) and MicroSMP (DO-219AD), which utilize 24% and 57% less PCB space, respectively. To reduce power losses and improve efficiency, the rectifiers feature low forward voltage drop down to 0.69 V.
TMBS and FRED Pt rectifiers in SlimSMAW package increase power density, efficiency and reliability
Vishay introduces new 2 A, 3 A and 5 A TMBS rectifiers and 100 V and 200 V FRED Pt ultrafast recovery rectifiers in the eSMP series SlimSMAW (DO-221AD) package with a low 1.0 mm profile. Footprint-compatible with the common SOD-128, the SlimSMAW package features larger lead widths and shorter lengths than devices in the SlimSMA for AOI systems and increased reliability. Available in AEC-Q101 qualified versions, the devices offer low forward voltage drop to reduce power losses and increase efficiency.
MicroBUCK and MicroBRICK regulators with PMBus interfaces and high peak efficiency
The Vishay Siliconix MicroBUCK SiC451 and MicroBRICK SiC951 combine high performance trench MOSFETs in compact 5 mm by 7 mm and 10.6 mm by 6.5 mm by 3 mm thermally efficient packages, respectively, with the SiC951 also offering an integrated inductor. Both devices support over 50 PMBus commands. Capable of supplying up to 30 A of continuous output current and offering peak efficiency up to 96%, the buck regulators' output voltage is digitally adjustable from 0.3 V to 5.5 V with 1% output voltage accuracy.
VRPower smart power stages increase efficiency and accuracy to lower energy costs for server farms and computing applications
The 80 A SiC820 and SiC830 feature integrated current and temperature monitors in the thermally enhanced PowerPAK MLP56-39L package. While solutions that monitor power consumption using inductor DCR sensing offer current reporting accuracy of 7%, the Vishay Siliconix solutions utilize low side MOSFET sensing for accuracy of less than 3%. This translates into better performance and improved thermal management in high current processors.
80 V TrenchFET Gen IV N-channel power MOSFET in the PowerPAK SO-8 single package increases efficiency
For power conversion topologies and switching circuitry, the Vishay Siliconix SiR680ADP combines on-resistance down to 2.35 mΩ typical at 10 V with ultra low gate charge of 55 nC and COSS of 614 pF. The resulting on-resistance times gate charge FOM is 12.2% lower than the closest competing product and 22.5% lower than the previous-generation device.
Fourth Generation 600 V EF series fast body diode MOSFET delivers industry-low on-resistance times gate charge FOM for power conversion applications
The Vishay Siliconix SiHH070N60EF slashes on-resistance by 29% compared with previous-generation devices while delivering 60% lower gate charge. The resulting on-resistance times gate charge FOM of 3.1 Ω*nC is 30% lower than the closest competing MOSFET in the same class. These values translate into reduced conduction and switching losses to save energy in telecom, industrial, computing and enterprise power supply applications.
40 V automotive grade power MOSFET saves space, increases reliability

Automotive grade AC and pulse metallized polypropylene film capacitors ensure compliance with AEC-Q200 Rev. D, withstand THB testing
With operating temperatures to 125° C, Vishay BC components MKP385e series devices ensure compliance with IEC 60384-17 and AEC-Q200 Revision D while withstanding temperature humidity bias (THB) testing of 60° C, 93% RH for 56 days at rated voltage. Offered in compact packages to increase density, the devices are ideal for hybrid and electric vehicles.
LVAC power capacitors with ESTAspring reduce assembly time and improve connection reliability for vibration-proof performance
While most tubular power capacitors feature an IP20 terminal block with a screw connection, the ESTAspring lever-operated spring terminal connection of the Vishay ESTA PhMKP series is completely screwless. This enables a faster and easier connection, and the continuous contact force ensures the highest level of contact reliability over the devices' entire lifetime.
