Its 154 V reverse standoff voltage means the protected line sees no leakage up to that DC level; above it the device breaks down at a minimum of 171 V and clamps at 246 V maximum during a 10/1000 µs surge pulse. That 246 V clamp is the voltage the downstream component must survive — a 250 V-rated MOSFET or capacitor has no margin here. The AEC-Q101 qualification certifies it for automotive stress levels — temperature cycling, high-temperature reverse bias, and ESD robustness — making it suitable for 12 V and 24 V vehicle electrical systems where load-dump and inductive kickback transients are common. ## DO-201AA axial package and through-hole mounting Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE180AHE3/51 is a through-hole part intended for point-to-point wiring or PCB mounting with lead bending. The axial body allows series insertion into a power rail — the cathode band marks the unidirectional orientation. ## Obsolete — sourcing through independent channels Vishay lists the 1.5KE180AHE3/51 as obsolete. No official successor order code is recorded in the lifecycle data. For a BOM that requires this exact AEC-Q101 TVS with a 154 V standoff and axial package, the procurement path is a per-lot quote against the required quantity.","metaTitle":"1.5KE180AHE3/51 Vishay TVS, 1500W, 154V Standoff, Axial","metaDescription":"Vishay 1.5KE180AHE3/51 TransZorb TVS, 1500W peak pulse, 154V standoff, 246V clamp, AEC-Q101, DO-201AA axial.
