Ultra-Compact 1x1mm DFN Package with ESD Protection & 250mΩ RDS(on)

MCC Semi is proud to announce our latest component with serious benefits: SI3134KU6. This 20V dual N-channel MOSFET was meticulously designed for high-speed switching. 

Its ultra-compact DFN1010 package only takes up 1x1mm of space while delivering a low input gate charge and ESD-protected gate input up to 2kV.

When component density counts, our new 20V MOSFET is the product for the job — whether it’s a computing, industrial, telecom, or consumer application. 

The newest star in our lineup leverages trench LV MOSFET technology and MCC reliability to offer engineers the ideal component for motherboards, charging circuits, automation controls, and more.
