Housed in a DO-201AA (DO-27) axial-lead through-hole package, it handles the thermal dissipation of a 1500 W pulse without the junction exceeding the -55°C to 175°C operating range. ## Sourcing an obsolete TVS — what to expect Because Littelfuse has discontinued the 1.5KE10-B, new-stock sourcing runs through independent surplus and broker channels — quantities are lot-specific, and availability is confirmed only at RFQ time. No pin-compatible direct replacement is listed; a BOM review should verify the standoff voltage and clamping requirements before substituting any alternative TVS diode.","metaTitle":"1.5KE10-B Littelfuse TVS Diode, 1500W, 8.55V Standoff","metaDescription":"Littelfuse 1.5KE10-B obsolete Zener TVS, 1500W peak pulse, 8.55V standoff, DO-201.
