The DO-201AA axial-lead package (also known as DO-27) is a through-hole form factor suited for point-of-use transient suppression on power rails or signal lines where a replaceable, high-surge component is preferred over a surface-mount alternative. ## Active production and sourcing posture No pin-compatible successor or second-source cross-reference is recorded — the 1.5KE440A A0G is the current order code for this voltage variant in the 1.5KE series.","metaTitle":"1.5KE440A A0G TVS Diode, 1500W, 602V Clamp, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE440A A0G Zener TVS, 1500W peak pulse, 376V standoff, 602V clamp.
