Device identity and key parametrics
The 1.5KE33A B0G: Its 28.2V reverse standoff voltage and 31.4V minimum breakdown voltage place it in the 28V rail protection class — suitable for clamping transients on 24V DC buses where the nominal rail sits below the standoff threshold. The through-hole DO-201AA (DO-27, axial) package handles the 1500W pulse without secondary heat sinking in most PCB layouts, provided the lead length is kept short to minimise inductance.
Store the bulk-packaged axial devices in a dry, ESD-safe bin — no moisture sensitivity level applies to the DO-201 leaded package.
