The operating junction temperature range spans -65°C to +150°C, covering the full under-hood and engine-bay thermal profile required by AEC-Q101 Grade 0 applications. The DO-214AB package is tape-and-reel packaged, compatible with standard pick-and-place assembly.","metaTitle":"1.5SMC18AHE3/9AT Vishay TVS, AEC-Q101, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC18AHE3/9AT Zener TVS diode, 1500W peak pulse, AEC-Q101 qualified, 15.3V standoff, DO-214AB SMC package.
