The 1.5KE9.1AHE3/51: It clamps a 112A surge current to 13.4V maximum.
This means the diode triggers before a 9.1V rail exceeds its absolute maximum — it protects sensitive ICs on a 7.7V nominal supply bus from transients up to 1500W. The DO-201AA axial package (DO-27 footprint) mounts through-hole and suits point-to-point or PCB wiring in modules where surface-mount reflow is not preferred.
