Therefore, any voltage rise due to increased current conduction is contained to a minimum, providing the best possible protection level.This LTKAK6 series can be combined in series or parallel solutions to offer various clamping levels and surge withstand options. The LTKAK6 SMT package provides a more compact PCB layout than typical through-hole AK TVS components. ## **Features** ## **Agency Approvals** |**Agency**|**Agency File Number**| |---|---| |AW|E128662| **Maximum Ratings and Thermal Characteristics** (TA=25°C unless otherwise noted) |**Parameter**
