Ask your AI about RUSB155 — and the rest of your design

Connect PartsPlan once to Claude, ChatGPT or another AI, and it reads the manufacturer's original datasheets for every part in your BOM or schematic, not just this one — answering with the document and page number.

e.g. “Using PartsPlan, check the datasheets for my whole BOM, and give the RUSB155 ratings and package dimensions with the pages.”
