With a peak pulse power rating of 1500W (1.5kW) and a clamping voltage of 59.3V at the peak pulse current, it protects downstream semiconductors from surges caused by inductive load switching, lightning, or ESD events. The 40.9V minimum breakdown voltage ensures the device starts conducting before the protected circuitry sees damaging overvoltage. The 36.8V reverse standoff voltage is the maximum continuous DC voltage the TVS can withstand without conducting — so this part suits 24V to 30V DC rails with margin.
onsemi lists the 1N6286A as Obsolete. For BOM lines that still specify this exact order code, supply is limited to existing stock in the independent channel.
Temperature range and application environments
The wide range also covers cold-start conditions down to -65°C.
