On the repair bench, that means you can extract the failed part and re-stuff the same holes without a board spin — the scorch mark tells you which one actually died. The 1.5KE series uses a standard lead spacing that matches most existing TVS footprints on 48V telecom and industrial boards. The wide temperature grade also means derating for high ambient is less aggressive than on a commercial-grade 85°C part — the 1500W peak pulse rating holds closer to its full value at elevated temperatures.","metaTitle":"1.5KE56A B0G TVS Diode, 1500W, 47.8V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE56A B0G unidirectional TVS, 1500W peak pulse, 47.8V standoff, 77V clamp.
