Its 7.79V minimum breakdown voltage and 12.1V maximum clamping voltage define the protection window for a 7.02V reverse standoff rail. The 124A peak pulse current rating tells you the surge it can absorb before the junction overheats. ## Temperature range and mounting Operating junction temperature spans -65°C to 175°C, which covers military and downhole applications where ambient heat is extreme. The DO-201AD axial leaded package requires through-hole mounting — plan for lead forming and a 1.0 mm diameter hole per lead on the PCB. No surface-mount variant in this order code. ## Lifecycle reality — obsolete onsemi lists the 1.5KE8.2AG as Obsolete. If your BOM still calls this exact code, confirm date code and moisture sensitivity before reflow; the axial body is not MSL-sensitive, but storage history matters for long-shelf parts. For new designs, plan a cross to an active 1500W axial TVS with a similar standoff voltage.","metaTitle":"1.5KE8.2AG onsemi Mosorb™ Zener TVS Diode, 1500W, DO-201AD","metaDescription":"1.5KE8.2AG from onsemi is a 1500W peak pulse Zener TVS in DO-201AD axial package.

The supplier device package is also listed as Axial. This is a two-lead leaded form factor, not surface-mount."},{"question":"What is the difference between 1.5KE8.2AG and 1.5KE8.2ARLG?","answer":"The difference is in the packaging suffix: 'G' typically denotes lead-free / RoHS compliant, while 'RLG' indicates tape-and-reel packaging with lead-free finish. Both share the same electrical ratings — 7.79V breakdown, 12.1V clamping, 1500W peak pulse. The 'RLG' variant is supplied on a reel for automated insertion; the 'G' variant is bulk. Both are obsolete per onsemi."},{"question":"What is the closest pin-compatible alternative to 1.5KE8.2AG in this Circuit Protection family?","answer":"Within the same 1.5KE series from onsemi, the 1.5KE8.2ARLG is electrically identical and pin-compatible — same DO-201AD package, same breakdown and clamping voltages. The only difference is packaging (reel vs bulk). Both are obsolete; for an active alternative, look at the 1.5KE8.2CA (bidirectional) or a similar 1500W axial TVS from another manufacturer with a 7.02V standoff."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/1.5KE8.2AG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/1.5KE8.2AG when reusing this data.
