Littelfuse Launches New LTKAK2-L Series High Power TVS Diodes in Surface Mount Package
Achieve robust circuit protection for high-power applications using 60-80% less PCB space
June 1, 2023
Littelfuse, Inc., an industrial technology manufacturing company empowering a sustainable, connected, and safer world, announced the release of its latest product, the LTKAK2-L Series High Power TVS Diodes. This surface mount solution addresses the market demand for automated PCB assembly process-compatible TVS diodes with a high surge rating.
By using one LTKAK2-L in place of either four or eight 15KPA or 30KPA axial-leaded TVS diodes, electronics designers can save 60% and 80% of PCB space respectively. View the video.
The LTKAK2-L Series TVS Diodes offer a compact, surface mount package compatible with automated PCB assembly processes. The smaller solution in a modified SMTO-218 package allows designers to achieve robust circuit protection with less PCB space than the available axial leaded solutions. The 2 kA surge current rating enables designs to comply with IEC-61000-4-5 Level 4 requirements, which protects numerous high-reliability AC and DC power supplies and their applications.
The LTKAK2-L Series SMD TVS Diodes are ideal for use in many high-power applications, including:
- Information Communication Technology (ICT)
- Industrial
- Avionics
- AC and DC power supplies, and
- High-power converters/power supplies
“This new product helps solve the key problem of high surge rating TVS diodes being in larger sized, axial leaded packages, which are not compatible with automated PCB assembly processes,” said Ben Huang, Senior Product Marketing Manager at Littelfuse. “The LTKAK2-L Series provides a compact surface mount solution that protects AC and DC power supply to achieve high reliability. This automated PCB assembly process-compatible TVS diode is a significant step towards making high-power TVS diodes more accessible to designers.”
