Its 8.5 V reverse standoff voltage means it will not conduct at the normal operating voltage of an 8.5 V supply, but it triggers at a minimum breakdown of 9.44 V to shunt overvoltage events to ground. Rated for 500 W peak pulse power, this part handles moderate surge events typical of general-purpose power, signal, and I/O protection in industrial and telecom equipment. ## Package and temperature – DO-214AC fit and thermal range Housed in the DO-214AC (SMA) package, this is a standard surface-mount footprint shared across the SMAJ series. No power-line protection feature – this is a unidirectional device for DC rails, not AC mains. Microchip lists the SMAJ8.5AE3/TR13 as Active.
