New 100 V Vishay Siliconix N-Channel TrenchFET(R) Power MOSFETs Featuring New ThunderFET(R) Technology Offer Lowest On-Resistan
MALVERN, PA--(Marketwire - February 24, 2011) - Vishay Intertechnology, Inc. (
The SiR870DP's low on-resistance of 7.8 milliohms at 4.5 V is the industry's lowest. This MOSFET also offers a very low on-resistance of 6 milliohms at 10 V. For designers, the device's lower on-resistance translates into lower conduction losses and reduced power consumption for energy-saving green solutions.
With its industry-low 208 milliohms-nC FOM at 4.5 V, the SiR870DP combines low conduction and switching losses for higher frequency and switching applications. For designers requiring an SO-8 packaged device, the Si4190DY's on-resistance of 8.8 milliohms at 10 V and 12 milliohms at 4.5 V, in addition to its FOM of 340 milliohms-nC at 10 V and 220 milliohms-nC at 4.5 V, is the industry's best.
The devices released today are optimized for primary side switching and secondary side synchronous rectification in isolated DC/DC power supply designs for telecom brick and bus converter applications. The MOSFETs' 4.5 V rating for on-resistance allows a wide range of PWM and gate driver ICs to be considered. By utilizing 5 V rated ICs, gate driver losses can be reduced and the overall design simplified by eliminating the need for a separate 12 V power rail.
The SiR870DP and Si4190DY are 100 % Rg and UIS tested. The MOSFETs are halogen-free according to the IEC 61249-2-21 definition and compliant to RoHS Directive 2002/95/EC.
Samples and production quantities of the new MOSFETs are available now, with lead times of 16 weeks for large orders. Follow TrenchFET power MOSFETs at [ http://twitter.com/vishayindust ].
