Active AEC-Q101 TVS for 12V rail protection
The 1.5SMC12CAHM3_A/H: This clamping margin keeps downstream silicon within its safe operating area during a 10/1000µs surge event, which is the standard telecom surge waveform per GR-1089 and ITU-T K.20.
1500W peak pulse in a DO-214AB footprint
Rated at 1500W for a 10/1000µs exponential waveform, this part absorbs transient energy that would otherwise damage sensitive ICs on a 12V bus. The DO-214AB (SMC) package is a standard surface-mount footprint for high-power TVS diodes.
Automotive-grade qualification and supply posture
Marked as Active in production, the 1.5SMC12CAHM3_A/H carries AEC-Q101 qualification, meaning it has passed the stress tests and reliability screening required for automotive-grade components. This includes temperature cycling, high-temperature reverse bias, and ESD robustness per the AEC-Q101 standard.
