This is the final production run — once existing stock is exhausted, no further units will be manufactured. For BOM lines that require this exact order code, the procurement window is now open; quantities are confirmed at RFQ. ## Through-hole axial footprint for board-level protection Housed in a DO-201AA / DO-27 axial leaded package, this part mounts through-hole — a standard footprint for high-power transient suppression where board real estate is not the constraint.","metaTitle":"1.5KE22A-E3/51 Vishay TransZorb TVS, 1500W, 18.8V Standoff","metaDescription":"Vishay 1.5KE22A-E3/51 TransZorb Zener TVS diode, 1500W peak pulse, 18.8V reverse standoff, 30.6V clamp.
