The 1500W rating means this part absorbs a single 1ms surge without failing — useful for protecting downstream converters and controllers in industrial control panels, automotive body modules, and battery-management circuits where the energy in a fault is bounded. ## DO-201 Axial Leaded — Through-Hole Mounting Housed in the DO-201AA / DO-27 axial leaded package (supplier device package DO-201), this TVS is intended for through-hole mounting on a PCB or wired point-to-point in a terminal block assembly. The axial leads suit hand-insertion or wave-solder processes; the bulk packaging means parts are loose in a tube or bag, not taped for automated reel feed. The package footprint is standard for the 1.5KE series — the lead diameter and body length match the common DO-201 outline, so replacement in an existing PCB layout is straightforward if the original part is a 1.5KE9V1 variant. No power line protection is claimed, so this part is not rated for AC mains transient suppression — it belongs on a DC bus or signal line. ## Obsolete — Sourcing Through Surplus Channels Diodes Incorporated lists the 1.5KE9V1A-B as obsolete. Sourcing is limited to surplus inventory held by independent distributors — lots are sealed reels or bulk tubes with date codes that trace to the final production runs. For a BOM line that requires this specific clamping voltage and package, the surplus channel is the only option. The 1500W peak pulse rating and 7.78V standoff are fixed — a substitute would need the same DO-201 footprint and Zener TVS characteristics to fit without board rework. Availability is lot-specific and confirmed at RFQ.","metaTitle":"Diodes Inc 1.5KE9V1A-B Zener TVS, 1500W, 7.78V Standoff","metaDescription":"Obsolete Diodes Inc 1.5KE9V1A-B Zener TVS diode, 1500W peak pulse, 7.78V reverse standoff, 112A Ipp, DO-201 axial.
