The 70.1V clamping voltage ensures downstream ICs rated for 75V or higher survive load-dump and inductive kickback events without secondary protection. The single bidirectional channel handles positive and negative transients in one package — useful for CAN bus, LIN bus, or sensor lines where polarity reversal is a risk. The tape-and-reel packaging (TR) suits automated pick-and-place assembly; store the reels in a dry environment per the MSL rating on the reel label.","metaTitle":"Bourns 1.5SMC51CA-Q TVS Diode, 1500W, DO-214AB","metaDescription":"Bourns 1.5SMC51CA-Q bidirectional Zener TVS, 1500W peak pulse, 43.6V standoff, AEC-Q101.
