New high power TVS diodes in surface mount package

Littelfuse, Inc has released its latest product, the LTKAK2-L Series High Power TVS Diodes. This surface mount solution meets the market demand for automated PCB assembly process-compatible TVS diodes with a high surge rating.

By utilising one LTKAK2-L instead of four or eight 15KPA or 30KPA axial-leaded TVS diodes, electronics designers can save 60% and 80% of PCB space, respectively.

The TVS diodes provide a compact, surface mount package compatible with automated PCB assembly processes. The smaller solution in a modified SMTO-218 package permits designers to accomplish robust circuit protection with less PCB space than the available axial leaded solutions. The 2kA surge current rating allows designs to comply with IEC-61000-4-5 Level 4 needs, which protects numerous high-reliability AC and DC power supplies and their applications.

"This new product helps solve the key problem of high surge rating TVS diodes being in larger sized, axial leaded packages, which are incompatible 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."

The series is ideal for use in many high-power applications, including ICT, Industrial, Avionics, AC and DC power supplies, and High-power converters/power supplies.
