The 7.02V reverse standoff voltage means it sits across a 5V or 6V DC rail without conducting under normal operation, then clamps transients at 12.1V maximum. ## What the key ratings mean for your BOM line For a 12V rail clamping at 12.1V, that translates to roughly 124A of surge current capacity — enough for most industrial and telecom secondary-side protection stages. The 7.02V reverse standoff is the maximum continuous DC voltage the TVS can block without degrading — your rail voltage must stay below this threshold during normal operation. The 7.79V minimum breakdown voltage ensures the device starts conducting before the rail sees damaging overvoltage. Operating from -65°C to 150°C junction temperature, this part fits outdoor telecom cabinets, engine-bay electronics, and military-grade equipment where ambient extremes are the norm. ## Sourcing reality — obsolete, no direct successor For existing designs that still specify this exact order code, sourcing runs through independent surplus and broker channels. ## Package and assembly fit The DO-201AA (DO-27) axial leaded package has a body diameter around 5.3 mm and lead diameter of 1.3 mm — standard for hand-solder or wave-solder through-hole assembly. The Tape & Reel (TR) packaging indicates the parts are supplied on a reel for automated insertion, though the quantity per reel is not listed in this record. Through-hole mounting means the PCB requires drilled plated holes — no reflow profile needed, but the assembly process is separate from surface-mount lines. The unidirectional channel means polarity matters: the cathode band must face the rail being protected.","metaTitle":"1.5KE8.2AE3/TR13 Microsemi TVS, 1500W, 12.1V Clamp, Obsolete","metaDescription":"Microsemi 1.5KE8.2AE3/TR13 Zener TVS diode, 1500W peak pulse, 12.1V clamp, 124A.
