The tape-and-reel packaging supports high-volume pick-and-place assembly. ## Clamping performance and selection fit The 49.7 A peak pulse current figure is the current at which the clamping voltage is specified — a lower surge current results in a lower clamp voltage, so the actual protection level depends on the source impedance of the transient. ## Automotive qualification and series identity The 1.5SMC22CA-Q belongs to the Bourns 1.5SMC-Q series, which carries AEC-Q101 qualification. The Q suffix in the order code denotes the automotive-grade variant of the standard 1.5SMC22CA.","metaTitle":"Bourns 1.5SMC22CA-Q TVS, 1500W, 30.6V Clamp, DO-214AB","metaDescription":"Bourns 1.5SMC22CA-Q bidirectional TVS diode, 1500W peak pulse, 18.8V standoff, 30.6V clamp.
