Product details

Clamping voltage and peak pulse rating

The 1.5KE43A B0G: The 36.8 V reverse standoff means the diode stays off below that rail voltage; once the transient pushes past 40.9 V breakdown (min), the Zener avalanche clamps hard at 59.3 V max.

The 1.5KE series is a standard JEDEC-registered TVS family, so second-source equivalents from other manufacturers (same DO-201 package, same 36.8 V standoff) exist on the market. Sourced to order against BOM quantities through independent distribution; availability confirmed at RFQ.

Frequently asked questions

What package does the 1.5KE43A B0G come in?

It is supplied in a DO-201AA (DO-27) axial leaded through-hole package, in bulk packaging.
