Therefore, any voltage rise due to increased current conduction is contained to a minimum, providing the best possible protection level. They can also be connected in series and/or parallel to create various capability and flexible protection solutions. The LTKAK10 SMT package provides a more compact PCB layout than typical through-hole AK TVS components. **Agency Approvals** OT **Features Agency Agncy File Number** E128662 • High Power TVS designed • Meet MSL level 1, per ~~ee LO~~ in a surface mount J-STD-020, LF maximun compact SMTO-218 peak of 245°C package • Halogen free and RoHS **Maximum Ratings and Thermal Characteristics** • Patent pending package compliant **(TA=25[O] C unless otherwise noted)** design • Pb-free E3 means 2nd - Pb-free E3 means 2nd - • Foldbak technology for level interconnect is superior clamping factor Pb-free and the terminal - • Tube or tape and reel pack finish material is tin(Sn) options available (IPC/JEDEC J-STD609A.01) - Foldbak technology for superior clamping factor **Parameter Symbol Value Unit** Operating Junction TJ -55 to 125 °C Storage Temperature Range TSTG -55 to 150 Current Rating[1] IPP 10 kA ~~EET EEE~~ Typical Thermal Resistance Junction to Lead R Ɵ JL 10 °C/W Typical Thermal Resistance Junction to Ambient R Ɵ JA 50 °C/W - Ideal for automatic pick and place assembly • UL Recognized and reflow process to compound meeting reduce the manufacturing flammability rating V-0 cost and increase the soldering quality as compared to axial leaded packages **Note:** **1.** Rated min IPP measured with 8/20μs pulse. ## **Functional Diagram** - Bi-directional **==> picture [46 x 8] intentionally omitted <==** **----- Start of picture text -----**
