This makes it suitable for general-purpose transient suppression on 24 VDC or 28 VAC rails where the normal operating voltage stays below 30.8 V and the system can tolerate a 52.4 V clamp during a surge event — typical in industrial control, telecom line cards, or power supply inputs. ## Obsolete — sourcing through independent channels Littelfuse has marked the 1.5KE36-B as obsolete. Sourcing is through independent distribution and surplus channels; quantities and pricing are confirmed at RFQ against the BOM line. ## Package and board-fit for through-hole assembly The DO-201AA (also known as DO-27) axial-leaded package suits through-hole mounting on single-sided or double-sided boards. The lead spacing and body diameter are standard for this power class — the axial leads drop into plated through-holes and can be wave-soldered or hand-soldered without special profile concerns. Bulk packaging means the parts ship loose in a bag or tube, not on tape and reel, so pick-and-place requires manual or tube-fed handling.","metaTitle":"Littelfuse 1.5KE36-B Zener TVS, 1500W, DO-201","metaDescription":"Littelfuse 1.5KE36-B obsolete Zener TVS diode, 30.8V standoff, 52.4V clamp, 1500W peak pulse.
