Power Line Protection is listed as No — this part is designed for signal-line and secondary protection on non-mains-power circuits, not for direct AC line entry protection. ## Thermal margin and package The DO-201AA (also called DO-27) axial body mounts through-hole with the cathode band marking the standard polarity convention — band towards the protected node in a reverse-bias orientation.","metaTitle":"Vishay 1N6279-E3/73 Zener TVS, 31.9V Clamping, DO-201AA","metaDescription":"Vishay 1N6279-E3/73 TransZorb Zener TVS, 1500W peak pulse, 17.8V standoff, 47A peak pulse current, DO-201AA axial.
