The DO-214AA (SMB) surface-mount package keeps the board footprint compact — the cathode band marks the bidirectional orientation, so polarity is not a concern during placement. ## Active production — no last-time-buy pressure The AEC-Q101 qualification means the part ships with full PPAP documentation and traceability, which is the baseline requirement for automotive Tier-1 BOMs and also simplifies qualification in industrial and telecom equipment that references automotive-grade screening.","metaTitle":"Bourns 1.5SMBJ30CA-H TVS Diode, 30V, 1500W, AEC-Q101","metaDescription":"Bourns 1.5SMBJ30CA-H bidirectional Zener TVS diode, 30V reverse standoff, 1500W peak pulse, AEC-Q101 qualified.
