Product details

TVS diode for rail and DC-bus clamping

The 1.5KE16ARL4 is a 1500 W peak-pulse-power transient voltage suppressor from onsemi's 1.5KE series, designed to clamp overvoltage transients on DC power rails and signal lines in industrial and telecom equipment.

Obsolete — plan the transition now

onsemi lists the 1.5KE16ARL4 as Obsolete. That means the manufacturer has stopped production and there is no committed last-time-buy window — any remaining stock in the channel is the final supply. For sustainment programs, the immediate action is to secure inventory against the BOM quantity while units are still available from distributors.

Sourcing and availability for the BOM line

Because this part is obsolete, availability is limited to existing distributor stock. We source the 1.5KE16ARL4 against an RFQ — no stock-holding claim, but we can check multi-source inventory and provide a quote for the quantity your BOM requires.

Frequently asked questions

How can I order 1.5KE16ARL4 or check stock?

Submit an RFQ with your target quantity. We source the 1.5KE16ARL4 from available distributor inventory — no live stock count on the page, but we confirm availability and pricing at quote time. The Obsolete status means the channel inventory is finite, so early commitment is advised.

Is 1.5KE16ARL4 obsolete?

Yes, onsemi lists the 1.5KE16ARL4 as Obsolete. Production has ceased and no last-time-buy is in effect.
