The bidirectional configuration means a single device protects both polarities on AC-coupled lines or symmetric signal pairs without needing two diodes back-to-back. ## Active production — no last-time-buy pressure This is a standard catalog TVS — not a niche or custom-screened device — so supply should track the normal production cycle of the 1.5KE series. ## Temperature range and derating context Rated for operation from -55°C to +150°C junction temperature — the full military-temperature window. The 1500W peak pulse rating applies at 25°C; above that, the device must be derated per the standard TVS derating curve (typically 1% per °C above 25°C, though the specific curve for the 1.5KE series should be referenced). At 150°C junction, the effective peak pulse power drops to roughly 810W — still adequate for most secondary-side protection in power supplies or I/O lines where ambient temperatures stay below 85°C. ## Where it fits — general-purpose board-level transient protection The 1.5KE8.2CA-G is classified for General Purpose applications — meaning it is not a dedicated automotive (AEC-Q101) or telecom (GR-1089) part, but serves the broad industrial and commercial transient-protection market. Typical uses include DC rail clamping on 5V or 6V supply buses, protection of signal lines in PLCs, sensors, and control panels, and surge suppression on low-voltage analog or digital I/O. The bidirectional nature suits it for AC-coupled data lines (RS-485, CAN bus) where the common-mode voltage can swing positive or negative relative to ground.","metaTitle":"Comchip 1.5KE8.2CA-G TVS Diode, 1500W, 7V Standoff","metaDescription":"Comchip Technology 1.5KE8.2CA-G bidirectional Zener TVS, 1500W peak pulse power, 7V reverse standoff, DO-201 package.
