The 1500 W rating is the peak pulse power the die absorbs in a single 10/1000 µs surge; repetitive transients require derating per the datasheet curve. Housed in a DO-201AA (DO-27) axial-lead package, through-hole mounted. The junction temperature range spans -55°C to +175°C, covering industrial and some automotive under-hood environments. The 1.5KE series package suffix — here -/54 — indicates the tape-and-reel packaging variant. For hand-placement or low-volume prototyping, the cut-tape option is the same die and electrical rating.","metaTitle":"1.5KE440CA-E3/54 Vishay TVS, 1500W Bidirectional, 376V","metaDescription":"1.5KE440CA-E3/54 Vishay TransZorb TVS, 1500W peak pulse, 376V standoff, 602V clamp.
