The 33.3 V standoff gives a 3.8 V margin above a typical 24 V automotive rail before the diode starts to conduct leakage current. No pin-compatible second-source is listed by the manufacturer, but the DO-214AB footprint is shared by many TVS diodes with similar ratings — parametric substitution is possible with a board-level surge review.","metaTitle":"1.5SMC39CAHR7G TVS Diode, 1500W, Bidirectional, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC39CAHR7G bidirectional TVS diode, 1500W peak pulse, 33.3V standoff, AEC-Q101 automotive grade.
