The single bidirectional channel means it clamps both polarities — no orientation to get wrong on the board. With a 7.78 V reverse standoff voltage, this TVS sits on a nominal 7.78 V or lower supply rail without conducting in normal operation. When a transient exceeds the 8.65 V minimum breakdown voltage, the Zener avalanche clamps the rail to 13.4 V maximum while shunting 117 A of peak pulse current. That 1500 W peak pulse rating means it absorbs a single 1 ms surge without failing — useful for industrial power inputs or automotive load-dump protection where the energy is short but high. The wide thermal margin means the clamping voltage shifts less across temperature compared to lower-rated parts, keeping the protected rail within tolerance over the full operating range.","metaTitle":"1.5KE9.1CA R0G TVS Diode, 1500W, 13.4V Clamp","metaDescription":"Taiwan Semiconductor 1.5KE9.1CA R0G bidirectional Zener TVS, 1500W peak pulse, 13.4V clamping, DO-201.
