It clamps transients on a 15.3V nominal rail to 25.2V maximum, protecting downstream semiconductors from surges caused by load dump, inductive kickback, or lightning coupling in general-purpose industrial and telecom equipment. ## Obsolete — sourcing options for the 1N6277A onsemi lists the 1N6277A as Obsolete. For a BOM line that must be filled, we source this part to order against your quantity — confirm the required date-code range and volume, and we will quote from available inventory or broker channels. The DO-201AD axial package is through-hole. ## Key ratings that define the protection window The reverse standoff voltage is 15.3V — the rail should never exceed this during normal operation. Breakdown occurs at a minimum of 17.1V, and the clamping voltage at peak pulse current is 25.2V maximum. The 1500W peak pulse power rating assumes a 10/1000 µs waveform; derate for shorter or longer pulses per the datasheet curve. Operating junction temperature range is -65°C to 175°C, suitable for outdoor or under-hood environments where the ambient can swing wide.","metaTitle":"1N6277A onsemi Mosorb™ Zener TVS Diode 1500W DO-201AD","metaDescription":"onsemi 1N6277A Mosorb™ Zener TVS diode, 1500W peak pulse power, 15.3V standoff, 25.2V clamp.
