The 38V gap between standoff and breakdown gives enough headroom for a nominal 342V bus to ride through normal ripple without the TVS conducting leakage, while still catching fast overvoltage events before the protected load sees 548V. ## Package and procurement profile DO-201AA axial — through-hole mount, mates into existing board layouts that use the 1.5KE family footprint.","metaTitle":"1.5KE400AH TVS, 1500W, 342V Standoff, AEC-Q101, DO-201","metaDescription":"1.5KE400AH from Taiwan Semiconductor: Zener TVS diode, 1500W peak pulse, 342V standoff, 548V clamp.
