For BOM lines that still specify this exact order code, supply is available through independent surplus and broker channels. Each lot is verified for date-code authenticity and RoHS compliance before shipment. ## Package and board-fit: DO-201AA axial Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE18HE3/54 mounts through-hole. The 1.5KE supplier device package code matches the standard axial footprint used across the 1.5KE series, so existing PCB layouts for sibling parts accept this device without board revision. The operating junction temperature range spans -55°C to +175°C, covering the full automotive under-hood thermal profile without derating concerns at the high end.","metaTitle":"Vishay 1.5KE18HE3/54 Zener TVS, 1500W, DO-201AA","metaDescription":"Obsolete Vishay 1.5KE18HE3/54 TransZorb TVS, 1500W peak pulse, 14.5V standoff, AEC-Q101 automotive.
