What this Zener TVS protects and where it fits
The 1N6280AG is an onsemi Mosorb™ Zener transient-voltage-suppression diode rated for 1500W peak pulse power at 10/1000 µs waveform. It clamps transients on a 20.5V nominal rail, with a minimum breakdown voltage of 22.8V and a maximum clamping voltage of 33.2V at rated peak pulse current. Packaged in an axial-lead through-hole case, it operates across -65°C to 175°C junction temperature — a range that suits industrial and some military/aerospace environments. This is a unidirectional device (single channel) with no power-line protection feature — intended for DC rail clamping, not AC mains.
onsemi lists the 1N6280AG as Obsolete. No official successor or replacement cross-reference is published by the manufacturer.
Package and mounting notes for BOM fit
The axial-lead package uses standard through-hole soldering; no moisture sensitivity level (MSL) concern.
