Rated for 1500W peak pulse power (1.5kW) at 10/1000µs waveform, with a reverse standoff voltage of 20.5V and a clamping voltage of 33.2V at the peak pulse current. Breakdown voltage minimum is 22.8V, ensuring the device starts conducting before the rail exceeds the protected circuit's tolerance. ## Package and temperature range Housed in a DO-201AD axial leaded package, the 1N6280A mounts through-hole on the PCB — the axial leads require manual or wave-solder assembly, not reflow. Operating junction temperature spans -65°C to 175°C, covering extreme industrial and automotive under-hood environments without derating at the high end. ## Lifecycle and sourcing posture For existing BOM lines, the part can be sourced through independent or excess inventory channels. Availability and pricing are confirmed per RFQ; no franchised stock is guaranteed at this lifecycle stage.","metaTitle":"1N6280A onsemi Mosorb™ Zener TVS – 1500W, DO-201AD, Obsolete","metaDescription":"onsemi 1N6280A Zener TVS diode, 1500W peak pulse power, 20.5V reverse standoff, DO-201AD axial package.
