New 500-V Vishay Siliconix N-Channel Power MOSFETs Feature Low 0.38-Ohm On-Resistance and Improved Gate Charge of 68 nC in TO-220AB,TO-220 FULLPAK, D2PAK, and TO-247AC Packages

MALVERN, PA--(Marketwire - October 14, 2010) -  Vishay Intertechnology, Inc. (NYSE: VSH) today released four new 500-V, 16-A n-channel power MOSFETs with ultra-low 0.38-ohm maximum on-resistance at a 10-V gate drive, and an improved gate charge of 68 nC, in the TO-220AB,TO-220 FULLPAK, D2PAK, and TO-247AC packages.

The low on-resistance of the SiHP16N50C (TO-220AB), SiHF16N50C (TO-220 FULLPAK), SiHB16N50C (D2PAK), and SiHG16N50C (TO-247AC) translates into lower conduction losses that save energy in power factor correction (PFC) boost circuits, pulsewidth modulation (PWM) half bridges, and LLC topologies in a wide range of applications, including notebook computer AC adapters, PC power supplies, LCD TVs, and open-frame power supplies.

In addition to their low on-resistance, the devices feature a gate charge of 68 nC. Gate charge times on-resistance, a key figure of merit (FOM) for MOSFETs used in power conversion applications, is a low 25.84 ohms-nC.

The new n-channel MOSFETs are produced using Vishay Planar Cell technology, which has been tailored to minimize on-state resistance and withstand high-energy pulses in the avalanche and commutation modes. Compared to previous-generation MOSFETs, the SiHP16N50C, SiHF16N50C, SiHB16N50C, and SiHG16N50C also offer faster switching speeds and reduced switching losses.

The devices are compliant to RoHS Directive 2002/95/EC and 100 % avalanche tested for reliable operation.

Samples and production quantities of the new power MOSFETs are available now, with lead times of 8 to 10 weeks for larger orders.
