Product details

Obsolete status and sourcing reality

For existing BOM lines or repair stock, the only sourcing path is the independent market — excess inventory, surplus lots, or broker-sourced material.

What the 1500W peak pulse rating means for your protection design

The 190V minimum breakdown voltage sets the clamping threshold: the device starts conducting at 190V and clamps the transient to a maximum of 274V at 5.5A peak pulse current. For a 171V reverse standoff, the diode stays off during normal DC rail operation up to 171V, then activates only when a surge exceeds that level.

Unidirectional channel and temperature range

Single unidirectional channel — cathode band on the DO-201AD axial package — so it protects one polarity rail. The through-hole DO-201AD body handles the thermal pulse of a 1500W surge without delaminating.

Frequently asked questions

How can I order the 1.5KE200A or check stock?

Since the 1.5KE200A is Obsolete, it is not available through standard distribution. We source it from the independent market — excess inventory, surplus, or broker channels. Submit an RFQ with your target quantity; we confirm availability and current pricing at quote time.

What is the replacement for the 1.5KE200A?

The evidence does not list an official onsemi successor. For a pin-compatible drop-in, look at the same 1.5KE series with a 200V breakdown rating — for example, the 1.5KE200A from other manufacturers like Vishay or Littelfuse, which share the DO-201AD package and 1500W rating. Confirm the breakdown voltage tolerance and clamping spec against your design margin.
