Lifecycle status and BOM planning
The 1.5SMC11C is listed as Obsolete by Littelfuse Inc. 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.
