It comes in a 20-VFQFN exposed-pad package (3.5x4.5 mm body), with a wettable flank option on the terminations — that flank means the side of the package pad is solderable, giving automated optical inspection (AOI) a clear fillet to check after reflow, which matters for automotive and industrial builds that require post-solder joint verification. For a CAN FD controller that will sit on a BOM for years, active status removes the sourcing risk of chasing EOL stock or qualifying a replacement mid-production. ## What the base product number tells the buyer If your BOM already calls out TCAN4550RGYT, the wettable flank is the differentiator — a standard QFN without the flank may still solder fine but will not pass the same AOI criteria, so confirm the inspection spec before substituting.","metaTitle":"TCAN4550RGYT CAN FD Controller, 20-VQFN, Active Production","metaDescription":"TI TCAN4550RGYT CAN FD Controller in 20-VQFN (3.5x4.5) package.
