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.","metaTitle":"Comchip 1.5KE9.1A-G TVS Diode, 1500W, 7.8V Standoff","metaDescription":"Comchip 1.5KE9.1A-G Zener TVS, 1500W peak pulse, 7.8V standoff, 13.4V clamp.
