With a 45.8A peak pulse current rating (10/1000µs), the diode can absorb substantial surge energy from lightning or inductive load dumps. The unidirectional channel (single) protects one polarity rail; for AC or bidirectional lines, two back-to-back or a bidirectional variant is needed. ## Lifecycle reality — obsolete, sourced to order Littelfuse lists the 1.5SMC24 as Obsolete.","metaTitle":"1.5SMC24 Littelfuse TVS Diode, 1500W, 20.5V Standoff","metaDescription":"Littelfuse 1.5SMC24 Zener TVS diode, 1500W peak pulse power, 20.5V standoff, 34.86V clamp, DO-214AB.
