That combination — 75 V standoff with a 1500 W peak pulse rating — is the standard transient-suppression class for automotive ECU input protection, where ISO 7637-2 load-dump pulses require a clamping device that survives the event energy without letting the downstream IC see more than its absolute-maximum rating. ## Automotive temperature grade and junction limits The DO-214AB (SMC) package is the standard automotive TVS footprint; it mounts directly to the PCB surface and conducts heat through the cathode tab to the board copper — the landing pad geometry sets the effective thermal resistance, not the package itself. ## Automotive qualification and compliance Listed under Automotive applications, which in Diotec's nomenclature designates AEC-Q101-qualification intent — the stress-testing sequence that covers temperature cycling, humidity, and surge exposure consistent with the automotive Electronics Council discrete-semiconductor qualification floor. The part is packaged in strip format for automated SMT assembly, and power-line protection is listed as no — this diode protects individual signal or power nodes at the board level, not a shared bus rail.","metaTitle":"1.5SMCJ75A-AQ TVS Diode, 75V Standoff, DO-214AB","metaDescription":"1.5SMCJ75A-AQ unidirectional Zener TVS, 75V reverse standoff, 121V clamping, 12.4A peak pulse, DO-214AB SMC.
