Diodes Incorporated has marked the SMCJ18A-13 as Obsolete. New designs should not specify this part; existing BOM lines rely on surplus or broker inventory. The DO-214AB (SMC) footprint is shared by many active TVS diodes, so a parametric replacement search should start with the same package and a 18 V standoff voltage.
Power line protection is not supported — this is a signal or DC rail clamp, not a mains transient suppressor.
