The datasheet notes no power line protection, which means this TVS is intended for secondary-side signal or low-power DC bus clamping, not for mains AC input surge suppression. ## Package and thermal envelope The 1500W peak pulse rating assumes a 10/1000µs waveform at 25°C; derating above 25°C follows the standard power-temperature curve for axial TVS diodes — at 175°C the peak pulse capability drops to roughly zero. ## Obsolete — sourcing through independent channels Available through independent distribution on a quoted-to-order basis. Stock is lot-specific and confirmed at RFQ; the buyer should verify date code and quantity against their BOM line before committing.","metaTitle":"Littelfuse 1.5KE75 TVS Diode, 1500W, 64.1V Standoff","metaDescription":"Littelfuse 1.5KE75 Zener TVS diode, 1500W peak pulse power, 64.1V reverse standoff, DO-201AA axial.
