The 1500W peak pulse rating assumes the standard copper-land pattern on the PCB — thermal performance degrades if the pad area is reduced below the datasheet recommendation.","metaTitle":"Bourns 1.5SMBJ51A TVS Diode, 51V, 1500W, DO-214AA","metaDescription":"Bourns 1.5SMBJ51A Zener TVS diode, 51V reverse standoff, 1500W peak pulse, AEC-Q101 automotive grade, DO-214AA SMB.
