DF3A5.6FU(TE85L,F) from Toshiba Semiconductor and Storage is a surface-mount TVS diode intended for circuit protection in compact electronic designs. Positioned in the Circuit Protection > TVS > TVS - Diodes category, this device is suited for general-purpose protection tasks where designers need a small SMD solution to help manage transient events on sensitive lines. Its 2-channel, zener-type configuration and USM package make it relevant for space-constrained consumer, industrial, and embedded products. Based on the provided specifications, the part is currently listed as Active, which supports ongoing design consideration, although lifecycle verification from the manufacturer is still recommended because the supplied lifecycle status is otherwise marked unknown. RoHS compliance information is not explicitly provided in the input data, so compliance should be treated as information not available until confirmed through Toshiba documentation or an official compliance certificate. For procurement teams, balanced supply-demand status is a positive indicator, but authorized-channel sourcing remains important given the stated open-market counterfeit risk.
