Vishay lists this part as Obsolete. ## Package and rework angle — DO-201AA axial Through-hole DO-201AA (DO-27) axial package — the body is large enough to hand-solder or rework with standard iron and solder wick. The banded cathode end is the only orientation mark; on a crowded board the band can be hard to read after wave solder, so a silkscreen outline on the PCB helps avoid a reverse-insertion mistake. Because the 1.5KE250-/73 is obsolete, new-stock supply runs through independent surplus channels.","metaTitle":"1.5KE250-E3/73 Vishay TransZorb TVS, 1500W, 360V Clamp","metaDescription":"Obsolete 1.5KE250-E3/73 Vishay TransZorb Zener TVS diode, 1500W peak pulse, 360V clamping, DO-201AA axial.
