Housed in a DO-214AB (SMC) surface-mount package, this part is a straightforward rework proposition. The large tab on the bottom side wicks heat into the board copper; a standard hot-air profile at 260°C peak with a preheat soak at 150°C lifts it clean without cooking the adjacent passives. Pin 1 is clearly marked by the cathode band — for a bidirectional part the orientation is symmetrical, so no polarity worry on placement. ## What the clamping voltages mean for your rail The 12.8V reverse standoff is the maximum DC voltage the TVS can sit across without conducting appreciable leakage — it is sized for a nominal 12V supply with tolerance. The 14.3V minimum breakdown is where the avalanche starts, and the 21.2V maximum clamping is the voltage the load sees at the full 71A peak pulse current. That 21.2V ceiling must stay below the downstream IC's absolute-max rating, or a secondary clamp is needed. The 1500W rating is the peak pulse power dissipation at 25°C ambient. Derate linearly above that — at 85°C the effective power handling drops to roughly 75% of the 1500W figure, so a 12V rail with a 1000W surge at 85°C still has margin.","metaTitle":"Panjit 1.5SMC15CA_R1_00001 TVS, 1500W Bidirectional","metaDescription":"Panjit 1.5SMC15CA_R1_00001 Zener TVS diode, 1500W peak pulse, 12.8V standoff, bidirectional, DO-214AB.
