The 1.5KE18C-B: The junction temperature range spans -55°C to 175°C, so the part can sit in a hot enclosure near a power supply or in an engine-bay environment without hitting the thermal ceiling. Power line protection is not built in — this is a general-purpose transient suppressor, not a mains-rated MOV — but for DC rails and signal lines it provides clean, fast clamping.
