AEC-Q101 qualification and a -55 to 150°C junction temperature range confirm it is suited for underhood and engine-bay environments where the ambient temperature can exceed 105°C. ## What the ratings mean for your BOM The 19.9 V clamping voltage ensures the protected circuitry — typically an ECU or sensor module rated to 36 V — stays below its absolute maximum during a surge. The 75.3 A peak pulse current at the clamping voltage gives the system margin for worst-case fault currents on a 12 V bus. DO-214AB (SMC) surface-mount package with 0.050-inch pitch is standard for 1.5 kW TVS diodes — the large copper tab on the bottom carries the thermal energy to the PCB pad. Layout should follow the recommended copper area for the peak pulse derating curve. ## Sourcing and lifecycle posture The -55 to 150°C operating range covers the full automotive temperature grade 0 envelope.","metaTitle":"SMCJ12CAQ-13-F Diodes Inc TVS, 1.5 kW, 12 V Bidirectional","metaDescription":"SMCJ12CAQ-13-F Diodes Inc 1.5 kW TVS diode, 12 V standoff, bidirectional, AEC-Q101, DO-214AB SMC.
