Market requirements for system protection products are higher

     Littelfuse focuses on circuit protection and has a growing global platform for power control and sensing. In recent years, in the field of power control, we have begun to strengthen the development of silicon carbide products, silicon carbide power technology can be said to be one of the most promising technologies in the global semiconductor market today. Littelfuse's silicon carbide Schottky rectifier diodes can work at higher switching frequencies and temperatures, achieving higher power density and improving work efficiency for customers. For the rapidly growing sensor market in the world, Littelfuse has successfully entered the automotive, medical, industrial, white power and other fields through the acquisition of ACCEL and Hamlin, and continues to introduce new products.

     For the rapidly evolving semiconductor technology, its increasingly complex functions and increasing sensitivity to external surges also provide opportunities for Littelfuse. For example, in the automotive electronics market, the corresponding protection technology development trend is to achieve the smallest possible size of the most stringent automotive standards of devices, such as ISO16750-2, ISO7637-2, and AECQ certification to provide customers with a comprehensive solution. Littelfuse, as a member of the AEC, is now advancing fuse's AEC-Q200 certification to provide customers with more reliable products. For the protection of EV(electric vehicle) high-voltage battery system, the battery pack voltage has a higher and higher trend, which puts forward more stringent requirements for the application of high-voltage and high-current fuses in automobiles. For the industrial market, Industry 4.0 and the Internet of Things are the development trend of this market, and the security protection in the industrial automation environment is also getting more and more attention.

     For the automotive electronics market, Littelfuse recently introduced the automotive-grade SLD8S Series Transient Voltage Suppression (TVS) diodes, which provide rated pulse peak power up to 7,000 W(10/1000μs) in a surface-mounted SMTO-263 package compatible with popular packages in the market. Up to 57V off-state voltage helps customers pass stringent ISO16750-2, ISO 7637-25a, 5b throw load surge tests for automotive electronics. Suitable for automotive electronics powertrain (power train), electronic control unit (ECU), battery management system (BMS), anti-lock braking system (ABS) and other applications, once launched, very popular with customers.

     For EV high voltage battery system protection, Littelfuse introduced the L50QS and L70QS, which are high-speed fuses with voltages up to 500V and 700V, in traditional North American tethered packages. In the near future, Littelfuse will also release test reports dedicated to vehicle vibration to enhance customer confidence in using Littelfuse products. Littelfuse has complete protection solutions for pico fuse for BMS harness protection, balanced sampling loops, and automotive CAN/LIN buses.

     For the industrial market, Littelfuse introduces the first varistor HMOV series to operate at ambient temperatures up to 125 ° C. It uses silicon coating technology for high-power applications with isolation voltages up to 2500V and inrush current absorption capacity up to 10kA(8/20µs). Suitable for industrial applications with high reliability performance.
