The 1.5KE300AHB0G: Its 256 V reverse standoff voltage and 285 V minimum breakdown voltage place it in the 300 V class for protecting 240 VAC or 300 VDC rails from transients. The 175 °C maximum junction temperature and -55 °C low end suit under-hood or high-temperature industrial environments where the ambient can exceed 125 °C.
