Product details

The 1.5KE180AG is a 1.5 kW transient-voltage-suppression (TVS) diode from onsemi, designed to clamp voltage spikes on power rails and signal lines in industrial, telecom, and automotive environments. 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Because the part is obsolete, new stock is limited to distributor and broker inventory.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.

Frequently asked questions

Is the 1.5KE180AG obsolete?

Yes, onsemi lists the 1.5KE180AG as Obsolete. No ongoing production.

What is the replacement for 1.5KE180AG?

A common pin-compatible replacement is the 1.5KE180A from Littelfuse or STMicroelectronics — same 1.5 kW rating, same 180 V standoff, same DO-201 package. Confirm the breakdown voltage and clamping curves against your application before swapping.
