The clamping voltage at 2A peak pulse current is 740V maximum, meaning the protected rail sees no more than 740V during a surge event before the TVS conducts and shunts the energy. This is the figure that matters for downstream component voltage ratings. Power line protection is not provided — this is a signal or DC bus protector, not an AC mains suppressor.","metaTitle":"1.5SMC540CA Littelfuse TVS Diode, 1500W, Bidirectional","metaDescription":"1.5SMC540CA Littelfuse Zener TVS diode, 1500W peak pulse power, 486V standoff, bidirectional, DO-214AB SMC.
