The axial body allows in-line or right-angle placement, and the lead spacing accommodates standard 0.300-inch (7.62 mm) hole patterns common in automotive ECU and power distribution boards. The junction temperature rating ensures the TVS can absorb repeated transients without derating in high-temperature environments. ## Obsolete — sourcing through independent distribution Vishay has marked the 1.5KE27CHE3/54 as obsolete. No official successor order code is recorded in the lifecycle data. The base product number 1.5KE27 covers multiple variants (different packaging, lead-free finishes, and qualification grades). The CHE3 suffix denotes the automotive AEC-Q101 qualified version in tape-and-reel packaging — the exact ordering code for high-reliability automotive builds.","metaTitle":"Vishay 1.5KE27CHE3/54 TVS Diode, 1500W, DO-201AA","metaDescription":"Vishay 1.5KE27CHE3/54 automotive AEC-Q101 TransZorb TVS, 1500W peak pulse, 21.8V standoff, DO-201AA axial.
