P-Channel MOSFET claims Lowest RDS(ON) in Its Class

April 28, 2014 by Jeff Shepard

Vishay Intertechnology, Inc. today introduced a new -30V, 12-V VGS p-channel TrenchFET® power MOSFET in the thermally enhanced PowerPAK® SC-70 package. Claiming the industry's lowest on-resistance at -4.5V and -2.5V gate drives for a -30V device in the 2 mm by 2 mm footprint area, the SiA453EDJ is designed to save space and increase power efficiency in portable electronics. The -30V VDS of the Vishay Siliconix device released today provides the headroom needed for over-voltage spikes, while its 12-V VGS enables lower on-resistance ratings of -3.7V and -2.5V for ultraportable, battery-operated applications.

The MOSFET is optimized for load and input over-voltage protection switches, battery chargers, and dc-dc converters in smartphones, tablet PCs, mobile computing devices, nonimplantable portable healthcare products, hard disk drives, and handheld consumer electronics including electric toothbrushes, shavers, scanners, and RFID readers. For these applications, the SiA453EDJ offers extremely low on-resistance of 18.5 mΩ (-10V), 23.5 mΩ (-4.5V), 26.0 mΩ (-3.7V), and 37.7 mΩ (-2.5V), and provides built-in ESD protection of 4000V.

The SiA453EDJ's on-resistance at -4.5V is 36% lower than the closest competing - 30V device, and 50% lower than the closest competing device with a 12-V VGS. The MOSFET's on-resistance at -2.5V is 46 % lower than the next-best 12 -V VGS device. These industry-low values allow designers to achieve lower voltage drops in their circuits and promote more efficient use of power and longer battery run times, while the device's compact PowerPAK SC-70 package saves critical PCB space.

The MOSFET is 100% Rg and UIS tested, halogen-free according to the JEDEC JS709A definition, and compliant to RoHS Directive 2011/65/EU. Samples and production quantities of the SiA453EDJ are available now, with lead times of 13 weeks for larger orders. Pricing for U.S. delivery only starts at $0.14 per piece in 100,000-piece quantities.
