General-purpose application tag covers AC line, DC bus, and signal-line transient suppression in industrial and commercial gear — not power-line protection rated, but fine for secondary-side or equipment-level surge clamping. ## Package, temperature, and deployment fit Through-hole DO-201AA (DO-27) axial package — the 1.5KE body handles the 1.5kW pulse without cracking, and the axial leads let it sit in a standard drilled PCB or terminal block with good thermal path to the copper pour. Supplied in Tape & Box (TB) — the /73 suffix signals the lead-free, RoHS-compliant finish and the TB packaging format for through-hole assembly lines. ## Lifecycle and sourcing — active, no substitution needed The 1.5KE440A-/73 is a standard catalog part, not a last-time-buy candidate. For BOM continuity, the 1.5KE440A base number is the same die in the same package; the suffix only changes packaging and plating.","metaTitle":"Vishay 1.5KE440A-E3/73 TVS Diode, 1.5kW, 376V Standoff","metaDescription":"Vishay 1.5KE440A-E3/73 TransZorb TVS diode, 1500W peak pulse, 376V standoff, 602V clamp, DO-201AA axial.
