DF3A3.3FU(TE85L,F) from Toshiba Semiconductor and Storage is an active TVS diode solution used in compact SMD protection designs where low-voltage transient suppression is needed. Positioned in the Circuit Protection > TVS > TVS - Diodes category, this device is suited for general-purpose protection on sensitive signal or interface lines in consumer, industrial, and embedded electronics. The provided specifications indicate a USM package, SMT mounting, 2 unidirectional channels, Zener-type behavior, and 115 pF capacitance at 1 MHz, making it relevant for engineers balancing board space and basic line protection requirements. Lifecycle status is listed separately as unknown, so design teams should verify current manufacturer support before committing to long-term programs. RoHS compliance information is not explicitly provided in the supplied data, so compliance should be treated as information not available pending confirmation from Toshiba or official product documentation. For procurement, balanced supply-demand status is a positive indicator, but counterfeit exposure in the open market suggests sourcing through trusted channels is important.
