The 376 V standoff suits 300 VDC bus rails or 277 VAC rectified lines where the nominal voltage sits below the standoff. ## Sourcing and lifecycle reality The base product number is 1.5KE440, so variants with different suffixes (e.g., 1.5KE440A, 1.5KE440CA) share the same die and package but differ in polarity or tolerance — confirm the exact AHA0G suffix for your approved vendor list.","metaTitle":"1.5KE440AHA0G TVS Diode, 1.5kW, 376V Standoff, DO-201","metaDescription":"1.5KE440AHA0G from Taiwan Semiconductor: 1500W peak pulse power, 376V reverse standoff, 602V clamp, AEC-Q101 qualified.
