Product details

Device identity and key ratings

The 1.5KE8.2AG is a unidirectional Zener TVS diode from onsemi's Mosorb™ series, rated for 1500W peak pulse power at 10/1000µs waveform. 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.

Frequently asked questions

What package does the 1.5KE8.2AG come in?

It comes in a DO-201AD axial through-hole package. The supplier device package is also listed as Axial. This is a two-lead leaded form factor, not surface-mount.

What is the difference between 1.5KE8.2AG and 1.5KE8.2ARLG?

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.

What is the closest pin-compatible alternative to 1.5KE8.2AG in this Circuit Protection family?

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.
