The 300V reverse standoff voltage means the diode does not conduct at normal operating levels up to that rail voltage. Breakdown occurs at a minimum of 333V, clamping the surge to a maximum 482V while conducting 3.2A peak pulse current. This clamping profile protects downstream semiconductors rated for 500V or less. ## Package and Board Integration Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE350AH mounts into a standard 0.100-inch pitch hole pattern. The axial body allows point-to-point wiring or PCB through-hole soldering — common in high-reliability power supplies and automotive junction boxes where surface-mount TVS devices might not survive repetitive thermal cycling. The wide junction temperature window also suits industrial and avionics applications where the ambient may exceed 85°C. AEC-Q101 qualification provides the documentation traceability required for automotive PPAP submissions — the device is manufactured on an IATF 16949-certified line with full lot traceability and reliability test data available on request.","metaTitle":"Taiwan Semiconductor 1.5KE350AH TVS Diode, 1500W","metaDescription":"Taiwan Semiconductor 1.5KE350AH Zener TVS diode, 1500W peak pulse power, 300V standoff, AEC-Q101 automotive grade.
