It clamps transients at 103V maximum, with a reverse standoff of 64.1V and a minimum breakdown voltage of 71.3V — typical for 75V rail protection in general-purpose industrial, telecom, and power-supply circuits. Housed in an axial-lead package, it is through-hole mountable and rated for operation from -65°C to 175°C junction temperature. ## Why the obsolete status matters for your BOM Any stock available is last-time-buy or surplus inventory. For a production BOM, plan a qualification and substitution now. ## Sourcing this part today The axial package is still common across the 1.5KE family, so a direct replacement from the same series (e.g., 1.5KE75A from another brand or the CA variant) is possible — confirm the unidirectional vs bidirectional requirement first.","metaTitle":"1.5KE75A onsemi Zener TVS – Obsolete","metaDescription":"onsemi 1.5KE75A Mosorb™ Zener TVS, 1500W peak pulse, 71.3V breakdown, DO-201AD axial.
