Rated for 1500 W (1.5 kW) peak pulse power, the 1.5SMBJ64A-H absorbs higher-energy surges than a 600 W SMBJ part — the difference matters when the transient source impedance is low, such as load-dump or inductive kickback on a 48 V automotive bus. The minimum breakdown voltage is 71.1 V (VBR), giving a guard band above the 64 V standoff before the diode starts conducting leakage current. ## Package, mounting, and production status Housed in the standard DO-214AA (SMB) surface-mount package — the same footprint as the SMBJ series — so a layout already using SMBJ parts accepts this device without a board revision. AEC-Q101 qualification means the part has passed the full suite of automotive stress tests (HTRB, H3TRB, temperature cycling, ESD) and is supported with PPAP documentation — a requirement for Tier-1 and OEM BOMs.","metaTitle":"Bourns 1.5SMBJ64A-H TVS Diode, 1500W, AEC-Q101, DO-214AA","metaDescription":"Bourns 1.5SMBJ64A-H Zener TVS, 64V standoff, 103V clamp, 1500W peak pulse, AEC-Q101 qualified.
