A 24 V bus or a 24 VDC sensor supply sits below the standoff, so the TVS stays invisible until a surge pushes the rail above 25.7 V. ## Package and field-swap reality DO-201AE axial, through-hole — the same footprint as the common 1.5KE series. Two leads, polarity band on the cathode end. No orientation ambiguity: the banded end goes toward the rail being protected, the other to ground. Can be swapped on site with basic tools — no hot air, no reflow profile. ## Temperature range for the full envelope No derating needed at 85°C ambient; the 1500 W peak pulse figure holds across the band.","metaTitle":"Micro Commercial Co 1.5KE27A-TP Zener TVS, 1500W, DO-201AE","metaDescription":"1.5KE27A-TP Zener TVS diode from Micro Commercial Co, 1500W peak pulse power, 23.1V standoff, DO-201AE axial.
