Texas Instruments has introduced a 60V N-channel FemtoFET power transistor that provides the industry's lowest resistance, 90% below traditional 60V load switches. Reducing power loss in end-systems. The CSD18541F5 is offered in a tiny 1.53x0.77x0.35mm silicon-based package that has an 80% smaller footprint than load switches in SOT-23 packages.
The CSD18541F5 maintains a typical on-resistance of 54mΩ and is designed and optimised to replace standard small-signal MOSFETs in space-constrained industrial load-switch applications. The tiny LGA package features a 0.5mm pitch between pads for easy mounting and reduced PCB space. The integrated ESD protection diode safeguards the MOSFET gate from over voltage.
Available in volume now from TI and its authorised distributors, the CSD18541F5 is packaged in a 3-pin LGA package and priced at $0.14 in 1,000 unit quantities.
