It is a through-hole part in a DO-201AD axial package, rated for a wide operating junction temperature range of -65°C to 175°C. ## Obsolete – what that means for your BOM onsemi has marked the 1.5KE7.5A as Obsolete. For a BOM line that depends on this exact order code, the options are a last-time buy from remaining distributor stock or a pin-compatible replacement from the same 1.5KE series family. ## Key ratings and what they mean for fit The minimum breakdown voltage is 7.13V — this is the voltage at which the device starts to conduct avalanche current. The clamping voltage at the peak pulse current of 132A is 11.3V, which is the maximum voltage the protected circuit will see during a surge event. The 1500W peak pulse power rating defines the energy-handling capability for a 10/1000µs waveform; a higher-energy transient will exceed the device's safe operating area.","metaTitle":"1.5KE7.5A onsemi TVS Diode – Obsolete","metaDescription":"1.5KE7.5A onsemi Mosorb™ Zener TVS, 1500W peak pulse, 7.13V breakdown, DO-201AD axial.

We can source remaining inventory from our supply chain and quote it to your BOM quantity. Submit an RFQ for current availability and pricing — no stock-holding claim is made here."},{"question":"What is the replacement for the 1.5KE7.5A?","answer":"The 1.5KE7.5A is part of the 1.5KE series. A direct pin-compatible replacement would be another 1.5KE device with the same breakdown voltage rating, such as the 1.5KE7.5A from a different date code lot or a cross from another manufacturer's 1.5KE-equivalent series. Confirm the breakdown voltage (7.13V min) and package (DO-201AD axial) match your application."},{"question":"Is the 1.5KE7.5A unidirectional or bidirectional?","answer":"It is a unidirectional TVS — one channel, cathode band on the axial package. For bidirectional clamping on the same rail, you would need the 'C' suffix variant (e.g., 1.5KE7.5CA)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/1.5KE7.5A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/1.5KE7.5A when reusing this data.
