The SLG59H1020V is a high‑performance, self-powered 50mΩ NMOS load switch with back‑to‑back reverse‑current blocking designed for all 4.5V to 20V power rails up to 3A. Using a proprietary MOSFET design, the SLG59H1020V achieves a stable 50mΩ RDSON across a wide input voltage range. Combining novel FET design and copper pillar interconnects, the SLG59H1020V package also exhibits a low thermal resistance for high‑current operation. Designed to operate over a -40°C to 85°C temperature range, the SLG59H1020V is available in a low thermal resistance, RoHS‑compliant, 1.6mm x 3.0mm STQFN package.
