Low Capacitance TVS Diode Series Offers Enhanced Lightning Protection for Aircraft Data Communications
Littelfuse, Inc. has introduced its new SMBLCE-HR/HRA, SMCLCE-HR/HRA, and SMDLCE-HR/HRA High-Reliability Low Capacitance TVS Diode Series. This cutting-edge series is engineered to provide superior protection for avionics systems, guarding against lightning and other overvoltage threats with unmatched reliability. This series is ideal for various avionics applications including flight control systems, full authority digital engine control, radar systems, and high speed data interfaces.
The SMBLCE-HR/HRA (600 W), SMCLCE-HR/HRA (1500 W), and SMDLCE-HR/HRA (3000 W) series are notable for their blend of high reliability and low capacitance, housed in compact JEDEC DO-214AA and DO-214AB packages. These diodes are meticulously crafted and rigorously screened to minimize early failures and maintain consistent performance, even under continuous surge conditions. They provide exceptional protection for sensitive avionics data lines with capacitance as low as 50 pF and power ratings from 600 to 3000 watts.
