Clamping is specified at 77V maximum at the peak pulse current — this is the voltage the downstream circuitry sees during a surge event. For a 48V bus with 80V-rated downstream capacitors, this clamp voltage leaves margin below the capacitor derating ceiling. ## Package and thermal handling for surge current Housed in a DO-201AE axial-leaded package, the 1.5KE56CA-TP is a through-hole part intended for point-to-point wiring or PCB mounting with the leads formed to the hole pitch. The large body diameter and thick leads carry the surge current without fusing — the 1500W rating assumes the leads are soldered into a board with adequate copper area to sink the heat from repetitive transients. The wide range means the TVS can be placed on a hot PCB near a regulator or in an outdoor enclosure without derating the peak pulse power at the high end — though the 1500W rating is derated linearly above 25°C per the datasheet curve. Packaging options include Tape & Reel for automated insertion and Cut Tape for prototype or low-volume builds. The reel quantity suits a production run; the cut tape lets a bench engineer qualify the part before committing to a full reel. ## Active lifecycle and sourcing posture The Power Line Protection field is marked No, meaning this TVS is not rated for AC mains surge protection — it belongs on DC buses and signal lines.","metaTitle":"1.5KE56CA-TP Micro Commercial Co TVS, 1500W, 47.8V","metaDescription":"1.5KE56CA-TP bidirectional Zener TVS diode, 1500W peak pulse power, 47.8V standoff, DO-201AE axial.
