DF3A6.8FUT1G from ON Semiconductor is a dual-channel unidirectional TVS diode designed for transient voltage protection in compact surface-mount automotive and embedded electronic designs. Housed in an SC-70-3 (SOT323) package, it is suited for space-constrained circuits that need protection against ESD and surge events on low-voltage signal lines. Based on the provided specifications, this device offers a 5 V stand-off voltage, 6.4 V minimum breakdown voltage, and 16 V maximum clamping voltage, making it relevant for protecting sensitive interfaces and control nodes. Its -55°C to 150°C junction operating range supports demanding automotive and harsh-environment applications. The listed product status is Active, which is favorable for ongoing design support, although the lifecycle status should still be confirmed through current manufacturer documentation. RoHS compliance information is not explicitly provided in the input, so engineers should verify RoHS and related material declarations with ON Semiconductor’s official datasheet or compliance statements before qualification.
