Malvern, PA — Vishay Intertechnology, Inc. [NYSE: VSH] has introduced a new TrenchFET 20 V n-channel MOSFET designed to save space, decrease power consumption, and extend battery usage in wearable devices, smartphones, tablets, and solid-state drives. Offered in a chipscale MICRO FOOT® package with an ultra-low 0.54 mm maximum height, the Vishay Siliconix Si8410DB provides the industry’s lowest on-resistance for any 20 V device in the compact 1 mm square footprint.
Optimized for use as a load switch, small-signal switch, and high-speed switch in power management applications, the Si8410DB features extremely low on-resistance of 37 mΩ @ 4.5 V, 41 mΩ @ 2.5 V, 47 mΩ at 1.8 V, and 68 mΩ @ 1.5 V. Compared with the closest competing devices in the CSP 1 mm square package, these ratings represent an improvement of 26 percent @ 4.5 V, 32 percent @ 2.5 V, 35 percent @ 1.8 V, and 27 percent @ 1.5 V. Compared with devices in the DFN 1 mm square package, on-resistance is 32 percent lower @ 4.5 V, 40 percent lower @ 2.5 V, 48 percent lower @ 1.8 V, and 43 percent lower @ 1.5 V. The device’s low on-resistance, ratings down to 1.5 V, and ± 8 V VGS provide a combination of safety margin, gate drive design flexibility, and high performance for lithium ion battery-powered applications.
The Si8410DB offers an extremely low on-resistance per area of 30 mΩ-mm square — 28 percent lower than the closest competing 20 V MOSFET in a 1 mm square plastic package — to save space and reduce battery power consumption in mobile applications. The device’s low on-resistance means a very low voltage drop at DC and pulse peak currents, so less power is wasted as heat. The combination of lower on-resistance and lower thermal resistance results in up to 45 and 144 percent lower temperature rise than the next-best devices in CSP and 1 mm square packages, respectively.
Samples and production quantities of the Si8410DB are available now, with lead times of 13 weeks for larger orders. Pricing for U.S. delivery only is $0.22 per piece in 100,000-piece quantities.
