That clamping voltage is the ceiling the downstream IC never sees, so selecting a standoff comfortably below the working rail but below the IC abs-max is the primary sizing move — 15 V sits cleanly above a 12 V nominal rail with margin for line variation. ## SMC/DO-214AB surface-mount footprint The DO-214AB package is the larger SMC variant — wider than the SMA (DO-214AC) footprint. The supplier device package is SMC/DO-214AB. The cathode band marks polarity on the tape strip orientation, which matters for automated pick-and-place programming. Junction temperature rating is -50°C to 150°C, so the thermal pad under the body must conduct heat to the PCB copper to stay within that window at full peak pulse current.","metaTitle":"Diotec 1.5SMCJ15C TVS Diode, 15V standoff, DO-214AB","metaDescription":"Diotec 1.5SMCJ15C unidirectional Zener TVS diode, 1500W peak pulse, 15V standoff, 26.9V clamping, DO-214AB SMC.
