Vishay Launches New LITTLE FOOT® Family in SC-70: Tiny Power MOSFETs Set Record for this Package Type
MALVERN, PENNSYLVANIA - February 15, 2000 - A new LITTLE FOOT® power MOSFET family was launched today by Vishay Intertechnology, Inc. with the release of the first such devices in the SC-70 package. Built on the proprietary Vishay Siliconix TrenchFET process, the devices released today set records for on-resistance in this package type, offering guaranteed specifications at gate drives as low as 1.8 V.
With a footprint measuring just 2.0 mm by 2.1 mm, the new 3-pin and 6-pin LITTLE FOOT SC-70 devices will serve as a space-saving replacement for SOT-23 and other larger power MOSFETs used for load switching and power management in cell phones, portable instruments, and notebook computers.
"Because it is smaller than a SOT-23 and easy to place on printed circuit boards, the SC-70 is becoming a very popular package type for space constrained designs," said Swapan Banerjee, Marketing Director at Vishay Intertechnology. "These LITTLE FOOT devices set a new standard for SC-70 performance with specifications that exceed any previous power MOSFETs in this package, and will thus help to accelerate this process."
The first 12 LITTLE FOOT SC-70 power MOSFETs include three single p-channel devices offering designers a choice of -8-V (Si1405DL), -12-V (Si1407DL), and -20-V (Si1403DL) breakdown voltages. On-resistance at a -4.5-V gate drive ranges from 125 milliohms for the -8-V device to 180 milliohms for the -20-V device, with maximum current handling of 1.8 A. Maximum power dissipation for the 6-pin SC-70 package is 625 mW.
The new LITTLE FOOT SC-70 power MOSFETs also include a series of dual p-channel, n-channel, and complementary n- and p-channel devices, any of which can be used to replace two single devices in the SOT-23. Offering the same choice of -8-V (Si1905DL), -12-V (Si1907DL), and -20-V (Si1903DL) breakdown voltages, the dual p-channel devices offer on-resistance in the range of 600 to 995 milliohms at a 4.5-V gate drive, while the complementary devices each pair a 385-milliohm n-channel MOSFET with a 600-milliohm or 995-milliohm p-channel. A dual n-channel rated at 20 V, Si1902DL, offers on-resistance of 385 milliohms.
Rounding up the new offerings are three single p-channel devices in a 3-pin SC-70 package. On-resistance ranges from 280 milliohms to 430 milliohms for devices offering a choice of of -8-V (Si1305DL), -12-V (Si1307DL), and -20-V (Si1303DL) breakdown voltages.
Samples and production quantities of all 12 new devices are available now, with lead times of 8 to 10 weeks for larger orders.
