This 50-to-72.7 V window is the operating region during a transient — the designer budgets the load's absolute-max rating above 72.7 V to avoid overstress. ## AEC-Q101 automotive qualification — the audit-ready credential For a Tier-1 ECU or an underhood module, the OEM auditor will ask for the PPAP documentation — the AEC-Q101 grade covers that requirement. Production status is Active per the manufacturer's lifecycle record. The DO-214AA (SMB) surface-mount package uses a standard JEDEC footprint with a 0.208-inch body length and 0.155-inch width. The cathode band marks the polarity on the bidirectional variant — both directions are symmetrical, so orientation is not critical. The tape-and-reel packaging (Cut Tape and full Reel options) feeds directly into pick-and-place lines with no special handling.","metaTitle":"Bourns 1.5SMBJ45CA-H TVS Diode, 1500W, 45V, DO-214AA","metaDescription":"Bourns 1.5SMBJ45CA-H automotive TVS diode, 1500W peak pulse, 45V standoff, AEC-Q101 qualified.
