The DO-201AA axial-lead package is a through-hole form factor that provides robust mechanical attachment in high-vibration environments compared to surface-mount alternatives. ## Obsolete — sourcing through independent channels Vishay has marked the 1.5KE180HE3/73 as Obsolete. The tape-and-box packaging is the original factory format; parts may arrive in cut tape or bulk depending on the lot. ## Breakdown and clamping window The minimum breakdown voltage is 162 V, ensuring the diode starts conducting before the rail exceeds the safe operating area of downstream components. The 258 V maximum clamping voltage at 5.8 A peak pulse current sets the worst-case transient voltage the protected circuit must survive — a 120 V rail with a 100 V margin to the clamp gives headroom for load-dump or inductive kickback events.","metaTitle":"Vishay 1.5KE180HE3/73 TVS Diode, 1500W, DO-201AA, AEC-Q101","metaDescription":"Vishay 1.5KE180HE3/73 TransZorb® TVS, 1500W peak pulse, 146V standoff, 258V clamp, AEC-Q101.

The 146 V standoff keeps it non-conducting under normal operation, and the 258 V clamp limits surge voltages. Typical applications include automotive ECU power inputs, industrial control power supplies, and any 120 V bus needing AEC-Q101-grade protection."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE180HE3-73","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE180HE3-73 when reusing this data.
