Vishay's high-voltage power MOSFETs combine low on-resistance and gate charge

Image of Vishay/Siliconix's SiHP18N50C/SiHG20N50C MOSFETsVishay's SiHP18N50C and SiHG20N50C N-channel power MOSFETs combine a 500 V rating with low 0.270 Ω maximum on-resistance at a 10 V gate drive. This low RDS(on) translates into lower conduction losses that save energy in power factor correction (PFC) and pulse width modulation (PWM) applications in a wide range of electronic systems, including LCD TVs, PCs, servers, telecom systems, and welding machines.
