Housed in the DO-201AA (DO-27) axial-lead package, the 1.5KE91A R0G is a through-hole part — the body and leads handle the 1500 W pulse without the thermal constraints of a surface-mount footprint. The axial leads let it sit off the board or mount in a terminal block, which helps heat dissipation during repetitive surge events.
