Automotive-grade TVS with 1500 W peak pulse rating
The 1.5KE27CHE3/54: Its 21.8 V reverse standoff voltage and 24.3 V minimum breakdown voltage define the protection threshold for 24 V nominal automotive buses.
Through-hole DO-201AA axial package for board-level integration
Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE27CHE3/54 mounts through-hole on the PCB. 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.
