The clamping voltage maxes at 32.5 V, which keeps downstream silicon within safe limits for most 15 V-rated ICs. ## DO-214AB (SMC) — rework and footprint Housed in a DO-214AB (SMC) package, this part is surface-mount with a standard footprint that reflows cleanly under a hot-air station. The SMC body has enough thermal mass to handle the 1500 W pulse without lifting pads, and the unidirectional marking (cathode band) is clear enough to orient by eye under magnification.","metaTitle":"STMicroelectronics SMCJ15A-TR TVS Diode, 1500W, 15V Standoff","metaDescription":"SMCJ15A-TR from STMicroelectronics: 1500W peak pulse power, 15V reverse standoff, unidirectional TVS in DO-214AB (SMC).
