Vishay Intertechnology Introduces New Little Foot Power MOSFET family
Vishay Intertechnology Inc. (Santa Clara, CA) recently introduced a new Little Foot power MOSFET family in the SC-70 package. The device, built on the Vishay Siliconix TrenchFET process, is claimed to set records for on-resistance in this package type, with specifications at gate drives as low as 1.8V.
According to Vishay, the first 12 Little Foot SC-70 power MOSFETs include three single P-channel devices offering designers a choice of -8V (Si1405DL), -12V (Si1407DL) and -20V (Si1403DL) breakdown voltages. On-resistance at a -4.5V gate drive ranges from 125 milliohms for the -8V device to 180 milliohms for the -20V device, with maximum current handling of 1.8A. Maximum power dissipation for the six-pin SC-70 package is 625MW.
The MOSFET family also includes 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. The dual P-channel devices offer on-resistance in the range of 600 to 995 milliohms at a 4.5V 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 20V offers on-resistance of 385 milliohms. The family also includes three single P-channel devices in a three-pin SC-70 package. On-resistance ranges from 280 mohms to 430 mohms for devices offering a choice of -8V (Si1305DL), -12V (Si1307DL) and -20V (Si1303DL) breakdown voltages.
"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."
Samples and production quantities of all 12 new devices are available now, with lead times of eight to 10 weeks for larger orders. In quantities of 100,000, pricing starts at $0.15 each.
