DF3A5.6FV,L3F from Toshiba Semiconductor and Storage is a dual-channel Zener-type TVS diode designed for compact circuit protection in space-constrained SMT designs. Housed in a small SOT-723/VESM package, it is suited for general-purpose protection of sensitive signal lines and low-voltage interfaces where board area is limited and fast protection components are required. With a minimum breakdown voltage of 5.3V and 65pF capacitance at 1MHz, this device can fit designs that need basic transient suppression without large package overhead. Typical use cases include consumer electronics, interface protection, portable devices, and embedded control boards. Lifecycle status is currently listed as unknown, so engineers should confirm long-term availability directly with Toshiba or an authorized source before locking it into new designs. Based on the provided specifications, this part is marked RoHS non-compliant, which may restrict use in EU-directed or environmentally regulated products unless a verified exemption or alternate version is confirmed through official manufacturer documentation.
