This new series of diodes will protect avionics equipment against thunderstrikes and other types of voltage damage.
Littelfuse has announced its new SMBLCE-HR/HRA, SMCLCE-HR/HRA, and SMDLCE-HR/HRA High-Reliability Low Capacitance TVS Diode Series, which offers protection against voltage threats to avionics equipment.
The key features of the SMxLCE-HR/HRA TVS Diode Series are its high power density, offering power ratings of 600, 1500, and 3000 watts, whilst being PCB layout friendly in DO-214AA and DO-214AB surface mount (SMC) packages. Low capacitance, with values below 50pF, high reliability, enhanced surge life and being regulatory compliant.
These three new diodes have been designed to be both highly reliable and low capacitance. Packed into compact JEDEC DO-214AA and DO-214AB packages, the new diodes offer a hybrid of well-suited qualities.
Charlie Cai, Director of Product Management, Protection Business, Semiconductor Business Unit at Littelfuse said: “Our new TVS diodes, with enhanced power ratings of 600 to 3000 watts in very compact surface-mount packages, will enable electronics engineers to design equipment that meets the high-grade regulatory requirements for protecting data lines.”
The diodes have capacitance values as low as 50 pF and power ratings ranging from 600 to 3000 watts. This helps protect avionics data lines and presents any damage occurring. During the manufacturing process, they have been tested to ensure consistent performance, ensuring that even under surge conditions the Diodes can still perform.
These diodes are suitable for a range of avionics equipment, including flight control systems, radar systems, Full Authority Digital Engine Control (FADEC) as well as any other high-speed data interfaces. It is designed to protect critical avionics equipment from overvoltage.
