That means the factory no longer produces it, so any new build or repair stock comes from surplus or distributor inventory — not a fresh wafer run. It clamps at 761.25 V max and has a reverse standoff voltage of 477 V, with a breakdown minimum of 477 V. Peak pulse current is 2.1 A under the same 10/1000 µs condition — that is the current the diode can sink during a transient before the clamping voltage rises. ## DO-201 axial package — field-swap friendly Through-hole mounting means it is a hand-solderable swap on a board — no hot-air station needed, just a soldering iron and a steady hand. ## Sourcing an obsolete TVS — what to expect Because the 1.5KE530C-B is obsolete, there is no manufacturer lead time to count on. Availability is lot-specific and confirmed at quote time through independent distribution channels. No official successor is listed on the record. If you need a drop-in replacement, the closest functional match would be another 1.5KE-series bidirectional Zener with a similar standoff voltage — but pin-compatibility is not guaranteed without checking the full datasheet.","metaTitle":"Littelfuse 1.5KE530C-B TVS Diode, 1.5kW, DO-201","metaDescription":"Littelfuse 1.5KE530C-B Zener TVS diode, 1500W peak pulse, 477V standoff, DO-201 axial.
