The device is supplied on Tape & Reel, compatible with automated pick-and-place. No power line protection feature is included — this is a signal- or secondary-side rail clamp, not a primary mains protector. Microchip lists the SMAJ43E3/TR13 as Active.","metaTitle":"SMAJ43E3/TR13 Zener TVS Diode, 43V, 500W","metaDescription":"SMAJ43E3/TR13 unidirectional Zener TVS, 43V reverse standoff, 76.7V clamp at 6.5A, 500W peak pulse.
