Rated for 1500 W of peak pulse power, this part handles substantial surge energy in a 10/1000 µs waveform, typical for industrial transient protection on signal or low-power supply lines. ## Lifecycle reality — obsolete, sourced through independent channels For a BOM line requiring this exact clamp voltage and package, a spot-market buy is the only path — expect to work with a broker who can verify date codes and screen for counterfeits. ## Package and integration note for the DO-201 axial footprint The DO-201AA / DO-27 axial body has a standard 0.042-inch lead diameter; the through-hole footprint requires 0.052-inch plated holes on a 0.400-inch lead spacing. Bulk packaging means parts are loose in a bag — no tape-and-reel for automated insertion. Hand placement or tube-fed insertion is typical for low-volume or rework scenarios. Bidirectional construction (single device, two Zener junctions back-to-back) eliminates the need to orient the part on the board — polarity is irrelevant, which simplifies assembly in high-vibration environments.","metaTitle":"Littelfuse 1.5KE8.2C-B Zener TVS, 1.5kW, Bidirectional","metaDescription":"Littelfuse 1.5KE8.2C-B Zener TVS diode, 1500W peak pulse, bidirectional, 7.02V standoff, DO-201 axial.
