The 33.3V minimum breakdown voltage means the device starts conducting before the rail exceeds its absolute maximum — a 30V supply with a 10% tolerance sits at 33V, leaving margin before the TVS triggers. Housed in the DO-214AA (SMB) surface-mount package, the 1.5SMBJ30A shares the same footprint as the smaller SMBJ and larger SMCJ series — a common PCB land pattern that accepts multiple TVS power levels. The -55°C to 150°C junction temperature range covers both outdoor telecom cabinets and under-hood automotive environments.","metaTitle":"Bourns 1.5SMBJ30A TVS Diode, 1500W, 30V, DO-214AA","metaDescription":"Bourns 1.5SMBJ30A Zener TVS diode, 1500W peak pulse power, 30V reverse standoff, 48.4V clamp at 31A.
