The CA suffix marks it as bidirectional — it clamps both polarities of transient voltage, which matters on the unsymmetrical rails common in 12V automotive systems where the supply domain floats around chassis ground. The 16V reverse standoff rating means the diode stays off and draws negligible leakage current during normal operation on a 12V rail — the 4V margin above nominal gives headroom for load dump and supply variation before the device begins to conduct. ## Automotive temperature grade and what it covers Junction temperature range is -50°C to 150°C, which maps to the upper end of the automotive grade band — this covers engine-compartment ambient spikes and cold cranking at temperature extremes without derating the clamping performance. Surface-mount SMC/DO-214AB package is the standard JEDEC footprint for this power class — reflow-profile compatible with standard automotive board assembly and the thermal pad under the cathode tab carries heat to the PCB copper for transient dissipation.","metaTitle":"1.5SMCJ16CA-AQ TVS Diode 17.8V 26V Clamping SMC","metaDescription":"Diotec 1.5SMCJ16CA-AQ bidirectional TVS diode, 16V standoff, 26V clamping, 57.7A peak pulse, automotive temp grade, SMC/DO-214AB.
