The SMC (DO-214AB) package is the mid-size surface-mount package in this family — larger thermal pad than the SMA (DO-214AC), which matters when the diode dissipates repeated surge energy; layout should follow the land-pattern recommendation in the datasheet to keep junction-to-ambient thermal resistance within the 150°C TJ limit.","metaTitle":"1.5SMCJ51A-AQ TVS Diode, 51V Standoff, 1.5kW Peak","metaDescription":"Diotec 1.5SMCJ51A-AQ unidirectional TVS diode, 51V standoff, 1.5 kW peak pulse, 82.4V clamping, AEC-Q automotive grade, DO-214AB SMC.
