The -55°C to 150°C junction temperature range covers under-hood and engine-bay environments where ambient temperatures exceed 105°C. ## Package and board-fit for DO-214AA (SMB) Housed in the standard DO-214AA (SMB) surface-mount package, the 1.5SMBJ48A-H uses the same footprint as other SMB-packaged TVS diodes — the cathode band marks the unidirectional orientation. Available in Tape & Reel (TR) and Cut Tape (CT) packaging, the part is suited for both high-volume pick-and-place assembly and prototype builds. The base product number 1.5SMBJ covers the full voltage range of the series; the -H suffix denotes the automotive-grade AEC-Q101 variant. ## Sourcing and compliance for the 1.5SMBJ48A-H The part carries AEC-Q101 automotive qualification, which includes compliance documentation for RoHS and REACH as standard for Bourns automotive-grade products.","metaTitle":"Bourns 1.5SMBJ48A-H TVS Diode, 1500W, 48V, AEC-Q101","metaDescription":"Bourns 1.5SMBJ48A-H Zener TVS diode, 1500W peak pulse power, 48V reverse standoff, AEC-Q101 automotive grade.
