1500 W surge clamp in a DO-201 axial body
The 1.5KE9.1A-G: In a DO-201AA (DO-27) axial-lead package, it handles a 13.4 V clamp at 111.94 A peak pulse current (10/1000 µs waveform). The single unidirectional channel and through-hole mounting suit it for general-purpose board-level surge protection where a soldered axial lead is preferred over surface-mount.
Clamping window and pulse capability
Reverse standoff is 7.8 V; breakdown starts at 8.65 V minimum, and clamping is limited to 13.4 V at the rated 111.94 A pulse current. That 5.6 V window between standoff and clamp gives the downstream circuitry a defined overvoltage ceiling during a surge event. Peak pulse power of 1500 W (10/1000 µs) defines the energy the part can absorb — useful for secondary protection on DC power inputs or signal lines where transients from inductive switching or lightning-coupled surges are expected.
