Any stock you find today is new-old-stock or surplus held by independent distributors. For a production BOM line, this part is no longer a viable long-term fit unless you have a secured inventory buffer. The base product number STD30N may share a die but the specific 'LT4' tape-and-reel variant is end-of-life. At 15 A load, dissipation from channel resistance alone needs the DPAK tab soldered to a copper plane for thermal relief. The 175°C maximum junction allows operation in high-ambient enclosures, but the 50 W power dissipation ceiling means thermal management – a good via stitch under the DPAK tab – is non-negotiable above 5 A continuous.","metaTitle":"STD30NF03LT4 N-Channel MOSFET, 30V 30A","metaDescription":"STD30NF03LT4 N-channel MOSFET from STMicroelectronics STripFET II series. 30V Vdss, 30A Id, 25mOhm Rds(on) at 10V.
