The SMB footprint is shared across the 1.5SMBJ family, so a single layout serves multiple voltage variants. Peak pulse current is 19.4 A under the 10/1000 µs condition — the clamping voltage at that current is 77.4 V, which defines the protection level for the downstream circuitry. ## Sourcing and compliance The 1.5SMBJ series shares the same package and footprint, so a different voltage variant within the family can serve as a functional replacement only if the standoff and breakdown voltages match the circuit requirement.","metaTitle":"Bourns 1.5SMBJ48CA-H TVS Diode, 1500W, Bidirectional","metaDescription":"Bourns 1.5SMBJ48CA-H bidirectional TVS diode, 1500W peak pulse, 48V standoff, AEC-Q101 automotive grade.
