A single bidirectional channel means one device protects both polarities without needing two diodes back-to-back, saving board space and reducing part count on the BOM. ## AEC-Q101 automotive qualification This part carries AEC-Q101 qualification, the automotive discrete semiconductor reliability standard. It is tested for temperature cycling, ESD sensitivity, and high-temperature reverse bias — necessary for Tier-1 PPAP submissions and under-hood or cabin electronics. ## Through-hole DO-201 package and sourcing posture Housed in a DO-201AA / DO-27 axial-lead package, the 1.5KE180CAHA0G mounts through-hole — the leadframe carries the 6.4A peak pulse current without the trace-width constraints of a surface-mount pad. Sourced through authorized and independent distribution; lead time and pricing confirmed at RFQ against the BOM quantity.","metaTitle":"Taiwan Semiconductor 1.5KE180CAHA0G TVS, 1500W","metaDescription":"1.5KE180CAHA0G TVS diode, 1500W peak pulse, bidirectional, AEC-Q101 automotive grade.
