Peak pulse power handling of 1500 W (1.5 kW) means the part absorbs the transient energy without degradation during the clamping event — a figure that matters for automotive input lines where load-dump transients can inject joules into the protection node in milliseconds. ## Junction temperature and automotive environment Junction operating range is rated -50°C to 150°C (TJ), covering the cold-start and engine-compartment thermal excursions typical in automotive deployments. The diode is listed for automotive applications, and the SMC (DO-214AB) package provides the thermal pad area needed to conduct the clamping dissipation to the board.","metaTitle":"1.5SMCJ22A-AQ TVS Diode 22V 35.5V Clamping DO-214AB","metaDescription":"Diotec 1.5SMCJ22A-AQ unidirectional TVS diode 1500W peak 42.3A 22V standoff automotive grade strip packaging.
