With 1500 W peak pulse power, it sits at the upper end of the axial TVS range — the kind of rating that handles inductive kick in motor drive snubbers or reverse-polarity events on higher-current rails, where a lower-rated TVS would fold under the transient energy. ## Wide thermal envelope and through-hole fit The -65°C to 175°C junction temperature range is the standout spec for this part — it exceeds what most commercial TVS diodes offer and suits equipment that runs in thermally demanding environments, including high-ambient enclosures or cold-start conditions. The DO-201AD axial package mounts in a standard PCB hole pattern and is wave-solderable — the through-hole form factor gives a mechanical anchor point that surface-mount TVS packages cannot in ruggedized or high-vibration assemblies. ## Sourcing posture — obsolete with no on-record successor For new designs this part is not available through authorized channels. For legacy maintenance and BOM continuity, independent distribution carries surplus and excess-stock inventory — lot traceability and counterfeit screening are the sourcing risk to manage against.","metaTitle":"Littelfuse 1N6277AG Zener TVS, 1500W Peak Pulse, DO-201AD","metaDescription":"Littelfuse 1N6277AG Mosorb Zener TVS diode, 1.5 kW peak pulse, 15.3 V standoff, 17.1 V breakdown, 25.2 V clamping.
