High Surge Rating SMD TVS Diodes

Littelfuse November 1, 2022

Littelfuse, Inc. (NASDAQ: LFUS), an industrial technology manufacturing company empowering a sustainable, connected, and safer world, announced the new SMTOAK2 TVS Diode Series. Many of today’s high-power, high surge rating TVS diodes are only available in axial leaded packages. The compact, 2 kA 8/20 μs rated, surface-mount package SMTOAK2 TVS Diode Series allows electronics designers to achieve a more robust transient voltage, overvoltage protection, and lightning protection system while using less printed circuit board (PCB) space.


The SMTOAK2 TVS Diode Series is ideal for high power density applications that require robust protection in a small footprint, including:


·      ICT, Medical, Industrial DC power supplies

·      High-power DC bus protection

·      DC power supplies used in exposed and harsh environments

·      Power over Ethernet (PoE) ports

·      Small Cell, Micro Cell, Remote Radio Units (RRU), Baseband Units (BBU)

·      High power density SiC and GAN-based DC/DC converters/power supplies


Global trends and regulatory requirements for higher efficiency power supplies, high current and high-speed MOSFET/IGBT designs are increasingly in demand,” said Ben Huang, Senior Product Marketing Manager at Littelfuse. “These fast-switching designs need protection against inductive kickback. By using the high-power SMTOAK2 TVS Diode Series, designers can achieve high reliability and robustness while reducing the required board space and assembly time.”
