Junction temperature is rated to 150 °C with a −55 °C lower limit — the wide range covers both cold-start automotive environments and high-density board layouts where adjacent components push the local ambient up. Surface-mount termination suits automated placement; the part ships on tape-and-reel or cut-tape for production or rework flows respectively. The thermal resistance of the SMC body is low enough that the 1.5 kW peak rating is survivable in the brief 10/1000 µs pulse window without exceeding the junction limit, but the PCB copper under the pad must be adequate for the continuous thermal path — a thermal pad or via array under the cathode tab is standard practice for designs that run near the temperature ceiling.","metaTitle":"Panjit 1.5SMCJ78CA_R1_00001, 78V TVS Diode, 1.5kW","metaDescription":"Bidirectional Zener TVS diode, 78V standoff, 11.4A peak pulse, 1.5kW peak power in DO-214AB SMC.
