Latest Vishay E-series MOSFET lowers conduction and switching losses

29 January 2019

Vishay Intertechnology Inc. has added to its fourth generation of 600 V E-series power MOSFETs. Providing high efficiency for telecom, industrial and enterprise power supply applications, the Vishay Siliconix n-channel SiHH068N60E reduces on-resistance by 27% compared with previous-generation 600 V E-series MOSFETs, while delivering 60% lower gate charge. This results in the industry’s lowest gate charge times on-resistance for devices in the same classSource: Vishay IntertechnologySource: Vishay Intertechnology.

Vishay offers a broad line of MOSFET technologies that support all stages of the power conversion process. With the SiHH068N60E and upcoming devices in the fourth-generation 600 V E-series family, the company is addressing the need for efficiency and power density improvements in the first stages of the power system architecture — power factor correction and hard-switched DC/DC converter topologies.

The SiHH068N60E features low typical on-resistance of 0.059 Ω at 10 V and ultra-low gate charge down to 53 nC. The device’s figure of merit of 3.1 Ω*nC is 12% lower than the closest competing MOSFET in the same class. The SiHH068N60E provides low effective output capacitances Co(er) and Co(tr) of 94 pf and 591 pF, respectively. These values translate into reduced conduction and switching losses to save energy.

Offered in the PowerPAK 8x8 package, the device is RoHS-compliant, halogen-free and designed to withstand overvoltage transients in the avalanche mode with guaranteed limits through 100% UIS testing.

Samples and production quantities of the SiHH068N60E are available now, with lead times of 10 weeks.
