Additionally, the ‘creepage’ distances of ST’s X02 series SCRs and Z01 series Triacs, which use this new package, will help meet the insulation requirements of the major safety standards for domestic and industrial electrical equipment (IEC 60370 and IEC 60335). A specific footprint can be designed on the PCB, where either SOT-223 or SMBflat packages can be soldered.
This solution guarantees full compatibility of both packages and provides flexibility at the production stage. The SMBflat package measures 3.95x4.6x1.1mm, it has a 3.4mm creepage distance and is RoHS compliant and halogen free.
