Circuit protection provider Littelfuse, Inc. has released the 450W SD05 unidirectional and SD05C bidirectional series of silicon-based TVS diode arrays designed to replace multilayer varistors (MLVs) as ESD protection.
According to the company, “the low dynamic resistance [of the devices] provides up to a 50 percent reduction in clamping voltage when compared with competing technologies.” The TVS diode arrays are capable of dissipating induced surge currents of up to 30A.
“The SD05 and SD05C Series are perfect solutions for medical, industrial, consumer and computing applications. They allow designers to add ESD and/or surge protection around the printed circuit board (PCB) as needed,” Chad Marak, director of the Littelfuse TVS Diode Arrays product line, said. “Their compact SOD-323 package fits right into the footprint of an 0805 MLV, allowing manufacturers to replace them in their designs with a SD05 or SD05C device without requiring a PCB or solder pad change.”
