That 1500W rating defines the surge energy it can clamp before the junction gives way — for a 7.78V standoff line, this part handles transients that would blow a lower-rated device. ## Clamping window and breakdown margin Reverse standoff voltage is 7.78V typical; the breakdown starts at 8.65V minimum, and clamping maxes at 13.4V at rated Ipp. That 5.6V window from standoff to clamp means the protected rail sees less than 14V during a surge — critical for 12V nominal bus protection where the downstream silicon must survive the clamp. Operating temperature spans -65°C to 175°C junction, which covers military and industrial thermal extremes without derating the peak pulse power at the hot end. ## Obsolete status and sourcing path onsemi lists the 1N6270ARL4G as Obsolete. For a BOM that needs this exact order code, the only sourcing channel is the spot market or excess inventory. We can quote against your quantity from available stock — no lead time from the fab, but we confirm availability at quote time. ## Package and mounting fit Through-hole axial DO-201AD package — the same footprint as the industry-standard 1.5KE series. The lead bend and hole diameter on the PCB match the 0.040-inch lead diameter; no board respin needed if you are replacing a 1.5KE7.5A or similar.","metaTitle":"1N6270ARL4G onsemi Mosorb™ Zener TVS Obsolete – Sourcing &","metaDescription":"onsemi 1N6270ARL4G Mosorb™ Zener TVS, 1500W peak pulse, 7.78V standoff, DO-201AD axial.

A functional cross would be another 1500W Zener TVS in DO-201AD with a 7.78V standoff, such as the 1.5KE7.5A from various manufacturers.
