For existing BOM lines, sourcing is through independent distribution channels. ## Key electrical ratings for circuit protection fit The breakdown voltage range starts at 9.95 V minimum, and the clamping voltage at peak pulse current (I_PP) is 16.38 V maximum. With a peak pulse current rating of 97.4 A, the device limits transient overvoltage to 16.38 V before the surge energy is absorbed. The single bidirectional channel protects one signal or power rail against both positive and negative transients, eliminating the need for two unidirectional devices in series. ## Package and deployment environment This temperature grade suits it for industrial, telecom, and automotive under-hood environments where ambient temperatures can reach 125°C. It is classified for General Purpose applications and does not include power line protection features.","metaTitle":"Littelfuse 1.5SMC11C TVS Diode, 1.5kW, 9.4V Standoff","metaDescription":"Obsolete Littelfuse 1.5SMC11C bidirectional Zener TVS, 1500W peak pulse, 9.4V standoff, DO-214AB.
