Vishay Releases Five New P-Channel Power MOSFETs

Vishay Intertechnology Inc. (Malvern, PA) released five new p-channel load switches (the Si1499DH, Si3495DV, Si3499DV, Si5499DC and Si8419DB), which are designed to offer low on-resistance at a 1.5 V gate drive. With a low threshold voltage and guaranteed specifications at a 1.5 V gate drive, the new devices eliminate the need for level-shifting circuitry and maximize the power-saving benefits of low operating voltages in battery-operated systems.

The new power MOSFETs work directly from 1.5 V core supply voltages with on-resistance as low as 45 mΩ. The five power MOSFETs include two devices in the LITTLE FOOT TSOP-6 with 20 V (Si3495DV) and -8 V (Si3499DV) drain-to-source breakdown voltages, and on-resistance ratings at a 1.5 V gate drive of 47 mΩ and 45 mΩ, respectively. Three additional devices (the -8 V Si8419DB, Si5499DC and Si1499DH) are available in the MICRO FOOT, 1206 8 ChipFET and SC-70 packages, respectively. Like the new LITTLE FOOT devices, they are rated for a 1.5 V gate drive.

Samples and production quantities of the new p-channel load switches are available now, with lead times of 12 weeks for larger orders. Pricing for US delivery in 100,000-piece quantities starts at $0.25.
