The clamping voltage peaks at 92 V when the surge current hits 17 A, so downstream silicon rated for 100 V or higher sees a safe voltage. ## Automotive-grade screening for under-hood reliability AEC-Q101 qualification puts this part through the same reliability stress tests — temperature cycling, high-temperature reverse bias, and ESD — that automotive modules require. That 175°C junction rating gives margin when the part is mounted near a hot engine block or inside a sealed ECU enclosure. ## Bidirectional protection, one part, no orientation A single bidirectional channel means the 1.5KE68CAH clamps equally on positive and negative transients — no need to worry about polarity when stuffing the board. The reverse standoff voltage is 58.1 V, so it stays off the line on a nominal 48 V rail and only starts conducting when the voltage exceeds the 64.6 V minimum breakdown. That window — 58.1 V standoff to 64.6 V breakdown — is tight enough to protect a 60 V-rated DC-DC converter without nuisance triggering from normal ripple.","metaTitle":"1.5KE68CAH TVS Diode, 1500W, DO-201, AEC-Q101, Taiwan Semi","metaDescription":"1.5KE68CAH bidirectional TVS diode, 1500W peak pulse power, 58.1V standoff, AEC-Q101 automotive grade.
