The reverse standoff voltage of 7.02V means this part protects a 5V or 6V rail (common in 5V logic or 6V sensor supplies) without conducting at nominal voltage. Breakdown starts at 7.79V minimum, so the rail sees no leakage until the transient exceeds that threshold. Bidirectional construction — single channel — means the same clamping characteristic applies to positive and negative transients, which simplifies layout on AC-coupled signal lines or bipolar supplies where polarity is not fixed. ## Package and thermal envelope Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE8.2CA R0G mounts through-hole. The axial body and 0.042-inch diameter leads suit hand-assembly or wave-solder processes; the lead spacing fits standard 0.300-inch pitch holes on a prototype board or production PCB. The 175°C max junction allows the device to absorb repetitive surges in a hot enclosure without derating the peak pulse power — the 1500W rating holds across the full temperature range, though derating curves in the datasheet apply above 25°C ambient. ## Sourcing and compliance status Marked as General Purpose for applications — no automotive-grade qualification (AEC-Q101) is stated, so for designs requiring that screening, a separate part variant may be needed. The DO-201 package is widely second-sourced across TVS families; pin-compatible alternatives exist from other manufacturers in the same 1.5KE footprint.","metaTitle":"1.5KE8.2CA R0G TVS Diode, 1500W, 7.02V Standoff","metaDescription":"Taiwan Semiconductor 1.5KE8.2CA R0G bidirectional TVS, 1500W peak pulse, 12.1V clamp, DO-201 package.
