Device identity and key ratings
The 1N6280A is a Zener TVS diode from the onsemi Mosorb™ series, designed for general-purpose transient voltage suppression in through-hole applications. 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.
