Operating junction temperature runs to 150 °C, so the board-side thermal pad and solder joint profile matter for long-term reliability — a junction that runs hot from poor pad adhesion will accelerate degradation under repeated transients.","metaTitle":"1.5SMCJ26A Diotec TVS Diode, 26V 1.5kW DO-214AB","metaDescription":"1.5SMCJ26A Zener TVS diode, 26V standoff, 42.1V clamping, 1.5 kW peak pulse, DO-214AB SMC active from Diotec.
