Sourcing is through independent surplus channels — the available stock is lot-specific and confirmed at RFQ. ## Protection window and physical fit The 94 V reverse standoff (working voltage) means the diode does not conduct below that rail — it protects a 94 V bus or a 90 V nominal line. Breakdown starts at 99.45 V minimum, clamping at 159.6 V maximum under the 10/1000 µs surge. That is a 65.6 V window from standoff to clamp — tight enough for a 100 V-rated downstream device. Package is DO-201AA (DO-27 axial), through-hole, single unidirectional channel. The axial lead form means it replaces an existing board layout with the same hole pattern — no footprint change needed if the original design used a DO-201 TVS. ## Sourcing posture for an obsolete line Littelfuse has marked the 1.5KE110 Obsolete — no last-time-buy window or successor part number is published. Availability, date code range, and lot traceability are confirmed at quote time. No franchised channel stock is claimed.","metaTitle":"Littelfuse 1.5KE110 TVS Diode, 1500W, 94V Standoff, DO-201","metaDescription":"Littelfuse 1.5KE110 Zener TVS diode, 1500W peak pulse, 94V reverse standoff, DO-201 axial.
