The junction operates from -55°C to 175°C, covering industrial and automotive under-hood ambient temperatures without derating at the lower end — at high ambient, the 1500 W rating assumes adequate lead-length and copper-pad heat sinking per the datasheet derating curve. The axial leads allow hand or wave soldering; the package body is non-hermetic but the junction is passivated, so standard conformal coating is sufficient for humid environments.","metaTitle":"Littelfuse 1.5KE150A TVS Diode, 1500W, 128V Standoff","metaDescription":"Littelfuse 1.5KE150A Zener TVS diode, 1500W peak pulse power, 128V reverse standoff, 207V clamping.
