The 434 V standoff means the diode draws negligible leakage below that DC voltage — it sits across a 380 V nominal bus without conducting. The 698 V clamp limits the transient peak to a level a downstream 800 V-rated MOSFET or capacitor can survive. ## Automotive grade and telecom fit Listed with an Automotive grade designation, the part is suited for 12 V/24 V vehicle systems where load-dump and ISO 7637-2 transients appear on the DC bus — the 434 V standoff covers the 24 V nominal rail with margin for the alternator's maximum regulated voltage. The Telecom application tag points to -48 V DC plant protection, where the 434 V standoff sits above the normal -48 V to -60 V range and the 698 V clamp absorbs the induced lightning surge per Telcordia GR-1089. Note the Power Line Protection field is marked No — this is not a primary AC mains protector; it guards DC rails and signal lines against secondary transients. ## Package and board integration The DO-201AE axial package (also known as R-6) is a through-hole form factor that handles the 1500 W pulse without the thermal impedance limits of a surface-mount equivalent. The leads are tin-plated copper for solderability into plated through-holes. The breakdown voltage is specified at 485 V minimum — the actual breakdown will fall between 485 V and the clamping voltage, so the diode begins to avalanche before the 698 V clamp is reached. This gives a predictable trigger point for the protection scheme.","metaTitle":"Micro Commercial Co 1.5KE510A-TP TVS Diode, 1500W","metaDescription":"1.5KE510A-TP Zener TVS diode, 1500W peak pulse, 434V standoff, 698V clamping.
