What the 1500W peak pulse rating means for your protection design
The 1.5KE16AHB0G: At that waveform, the device clamps a 70A peak pulse current to 22.5V maximum, meaning a 13.6V nominal rail sees the surge voltage held below the downstream component's abs-max rating.
Automotive qualification and temperature envelope
The 15.2V minimum breakdown voltage (the point where the diode starts to avalanche) sits 1.6V above the standoff voltage, giving a clean guard band against nuisance triggering from supply ripple or load-dump transients that stay within the normal operating range.
