Compared to the other power semiconductor devices (IGBT, Thyristor... built on a patent-pending p-channel technology that reduces device on-resistance to as low as 5 milliohms in the PowerPAK(R) SO-8.
Used as load switches, the p-channel power MOSFETs built on the new technology will help to reduce power consumption and the board area required for power components in cell phones, PDAs, notebook computers A laptop computer that weighs in a range from five to seven pounds. The term originated when laptops were routinely more than 10 pounds, and those that became lighter were placed in a special "notebook" category. In practice, notebook computer and laptop computer are synonymous. , and other compact, battery-operated products. In these systems, p-channel MOSFETs perform an essential role by turning off features such as the display or the power amplifier Power amplifier
The final stage in multistage amplifiers, such as audio amplifiers and radio transmitters, designed to deliver appreciable power to the load. when these are not being used, or by switching the system from active mode to sleep mode, and thus saving on battery life.
Siliconix was the first supplier to introduce TrenchFET technology into the market. With these new devices, the company adds to a rich patent portfolio, which includes both n-channel and p-channel TrenchFETs.
Siliconix is using the new p-channel technology to upgrade all of its leadership single-channel and dual-channel 12-V, 20-V, and 30-V p-channel MOSFETs. Devices built on the new technology will be available in all LITTLE FOOT(R) small-outline package types (SO-8, TSSOP-8, TSOP-6, and SOT-23) as well as in the leadless, thermally enhanced PowerPAK SO-8 and 1212-8 packages, which are fast becoming the industry benchmark for power MOSFET performance.
The first 10 devices in the new family include single-channel, -12-V load switches in the PowerPAK 1212-8 and SOT-23; -20-V devices in the LITTLE FOOT SO-8 and TSSOP-8; and -30-V devices in the PowerPAK SO-8 and TSOP-6.
On-resistance for the -12-V Si7407DN, packaged in the 3.3-mm by 3.3-mm PowerPAK 1212-8, is just 12 milliohms at -4.5 V, a 25% improvement over the previous state of the art for this package type. In addition to saving space, the PowerPAK 1212-8 dissipates up to 3.8 W of power, nearly double the level of any MOSFET (Metal Oxide Semiconductor Field Effect Transistor) The most popular and widely used type of field effect transistor (see FET). MOSFETs are either NMOS (n-channel) or PMOS (p-channel) transistors, which are fabricated as individually packaged device with a TSSOP-8-size footprint or smaller. Thermal resistance of just 1.9 degrees Celsius per Watt allows space requirements to be reduced in portable electronics without increasing "hot spots hot spots

The first LITTLE FOOT TSOP-6 devices built on the new p-channel technology include the single-channel, 30-V Si3483DV. The Si3483DV is rated for maximum on-resistance of 53 milliohms at 4.5 V, a 28% improvement over the next-best device on the market. Maximum current handling for the device is 6.2 A.
The -20-V Si4423DY, the first SO-8 device utilizing the new p-channel technology, is rated at 7.5 milliohms at 4.5 V and 11.5 milliohms at 1.8 V, improvements of 12% and 18%, respectively, over the next-best devices. The Si7451DP is the first -30-V, p-channel device in the PowerPAK SO-8. On-resistance for the device is just 5 milliohms at 10 V, with a maximum VGS VGS Videregående Skole (Norwegian school)

In the TSSOP-8 package, the new -20-V Si6413DQ is rated for an on-resistance value of 16 milliohms at 1.8 V, a 26% improvement over the next-best device, and for maximum current handling of 8.8 A. The newest SOT-23 device built on Vishay's patented p-channel technology is the Si2333DS, a -12-V device that surpasses competing devices by 26% with on-resistance of 59 milliohms at 1.8 V.
In addition to these single-channel devices, the new power MOSFET family also includes dual-channel devices in the PowerPAK SO-8, LITTLE FOOT SO-8, PowerPAK 1212-8, and TSSOP-8.
Released in the PowerPAK SO-8 is the -30-V Si7945DP, rated for an on-resistance of just 31 milliohms at 4.5 V and a maximum VGS of 20 V. The -12-V Si4933DY, a new dual-channel device in the LITTLE FOOT SO-8, is rated for 4.5 V, 2.5 V, and 1.8 V, with a 27% better on-resistance at 1.8 V -- just 22 milliohms -- than the nearest competing device.
The new Si7909DN, a space-saving, -12-V PowerPAK 1212-8 device, offers low on-resistance of 37 milliohms at 4.5 V, as well as high power dissipation Dissipation
