The 1500W rating is the 1.5 kW peak pulse rating that puts this part in the mid-range of the SMC-package TVS family — adequate for secondary protection on IO lines and local supply rails in industrial and consumer equipment, not a primary lightning-grade bus protector. ## SMC package, mounting, and thermal margin The DO-214AB (SMC) package is the standard surface-mount footprint for 1500W TVS devices — it gives the thermal pad area under the body that the 1500W transient rating requires. Soldering is reflow-profile compatible with standard SnPb and lead-free paste schedules.","metaTitle":"1.5SMCJ12C Diotec TVS Diode, 1500W Peak, 12V Standoff","metaDescription":"Diotec Semiconductor 1.5SMCJ12C unidirectional TVS diode, 1500W peak pulse, 12V standoff, 22V clamping.
