The 1.5KE82A-E3/73: The 1500 W rating is derated linearly above 25°C — at 175°C the peak pulse power drops to zero, so the thermal path from the axial leads to the PCB copper is the real limiter in sustained fault conditions.
This part is sourced through authorized and independent distribution channels.
