They are used for surges below 3000 W 10/1000 μs. This planar technology makes it compatible with high-end equipment and SMPS where low leakage current and high junction temperature are required to provide reliability and stability over time. **DS8598** - **Rev 7** - **January 2022** For further information contact your local STMicroelectronics sales office. www.st.com **SMC30JxxA, SMC30JxxCA Characteristics** ## **1** ## **Characteristics** **Table 1.
