No official successor order code is recorded — the 1.5KE series is broad, and replacement requires matching the breakdown voltage (8.17 V min) and bidirectional configuration. Available through independent distribution on a quoted-to-order basis. Reel quantities (Tape & Reel, TR) are typical; date codes and lot traceability confirmed at RFQ. This is a last-time-buy / surplus channel — no manufacturer lead time applies.","metaTitle":"Littelfuse 1.5KE9.1C TVS Zener, 1500W, 7.78V Standoff","metaDescription":"Littelfuse 1.5KE9.1C bidirectional Zener TVS, 1500W peak pulse, 7.78V standoff, 14.07V clamp.
