The -55°C to 175°C operating junction temperature range supports deployment in engine bays and other high-ambient environments. ## Obsolete — sourcing through independent channels For existing BOM lines, the part can be sourced through independent surplus and broker channels. ## Package and board-fit for legacy designs The 1.5KE24HE3/54 is supplied in a DO-201AA (DO-27) axial-lead through-hole package. The through-hole mounting suits point-to-point wiring, terminal blocks, or legacy PCB layouts where surface-mount reflow is not available. The axial body is rated for the full 1500W pulse without derating at 25°C lead temperature. The part is unidirectional with a single Zener TVS die.","metaTitle":"1.5KE24HE3/54 Vishay Zener TVS, 1500W, AEC-Q101, Obsolete","metaDescription":"Vishay 1.5KE24HE3/54 Zener TVS diode, 1500W peak pulse, AEC-Q101 qualified.
