The -55°C to 150°C junction temperature range covers under-hood and engine-bay thermal profiles. The AEC-Q101 qualification confirms the part has been tested for high-temperature reverse bias (HTRB), temperature cycling, and moisture resistance — relevant for an ECU or sensor module that sees both cold cranking and hot soak conditions. The SMB footprint is standard across the 1.5SMBJ series, so a single PCB layout can serve multiple voltage variants by populating the appropriate breakdown voltage part.","metaTitle":"Bourns 1.5SMBJ15CA-H TVS Diode, 1500W, AEC-Q101, DO-214AA","metaDescription":"Bourns 1.5SMBJ15CA-H automotive TVS diode, 1500W peak pulse, 15V standoff, AEC-Q101 qualified.

The 1.5SMBJ15CA-H is the automotive AEC-Q101 qualified version; the non-automotive 1.5SMBJ15CA shares the same electrical characteristics but lacks the AEC-Q101 qualification.
