Rated for 1500 W peak pulse power, this part protects 33.3 V nominal rails from surges up to that energy level — common on 24 VDC buses with margin for the reverse standoff voltage. Breakdown occurs at a minimum of 37.1 V, ensuring the diode stays off below the rail voltage and only conducts during an overvoltage event. The DO-214AB (SMC) footprint is shared with the supplier device package designation SMCJ — the same land pattern serves both.","metaTitle":"1.5SMC39CA Littelfuse TVS Diode, 1500W, Bidirectional","metaDescription":"Littelfuse 1.5SMC39CA bidirectional TVS diode, 1500W peak pulse power, 33.3V standoff, DO-214AB SMC package.
