These devices are more generally used against surges below 1500 W (10/1000 μs). The 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. SMCJ are packaged in SMC (SMC footprint in accordance with IPC 7531 standard). TM: Transil is a trademark of STMicroelectroniocs K A Unidirectional Bidirectional SMC (JEDEC DO-214AB) www.st.com
