DF3A5.6LFV(TPL3,Z) from Toshiba Semiconductor and Storage is a surface-mount TVS/Zener diode device designed for circuit protection in compact electronic designs. Positioned in the TVS - Diodes category, it is suited for general-purpose protection tasks where designers need low-capacitance behavior, small-package integration, and dependable suppression support around sensitive signal or power nodes. With a VESM package, SMD mounting, 3.5 V stand-off voltage, and 5.3 V minimum breakdown voltage, it can be considered for portable electronics, consumer equipment, interface protection, and other space-constrained applications requiring dual unidirectional channels. The listed product status is Active, which supports ongoing design consideration, although the broader lifecycle field is marked as unknown and should be confirmed through current manufacturer documentation. RoHS compliance information is not explicitly provided in the supplied specifications, so compliance status should be treated as information not available pending official datasheet, declaration, or manufacturer confirmation before production release.
