Its 180 V standoff voltage makes it a common choice for 120 VAC secondary-side protection and DC bus clamping in 150 V systems. onsemi has marked the 1.5KE180AG as Obsolete. No further production runs are planned. If you have this part on a BOM, you need a replacement or a last-time-buy strategy before existing stock dries up. ## Sourcing the 1.5KE180AG today Because the part is obsolete, new stock is limited to distributor and broker inventory. We can source the 1.5KE180AG against an RFQ — confirm quantity and date-code requirements at quote time.","metaTitle":"1.5KE180AG onsemi TVS Diode – Obsolete","metaDescription":"1.5KE180AG onsemi TVS diode, 1.5 kW, 180 V standoff.
