The SMC package thermal resistance is governed by the pad geometry on the board; Panjit specifies the package but not a θJC on the face sheet, so the board-level thermal design follows the standard DO-214AB land pattern recommendations. ## Package and sourcing posture DO-214AB (SMC) is a standard 2-pin surface-mount footprint — compatible with the common 1.5SMC landing pattern, so second-source equivalents in the same package are generally pin-compatible if the clamping specs match the application window.","metaTitle":"1.5SMC9.1A_R1_00001 TVS Diode, 1500W Peak, 7.78V Standoff","metaDescription":"Panjit 1.5SMC9.1A unidirectional TVS diode, 1500W peak pulse, 7.78V standoff, 13.4V clamping.
