New Generation Low On-Resistance, Low Gate Threshold MOSFET   Selection Guide

GKI / DKI Series

Low on resistance and low gate threshold combined to realize improved switching performance(FOM)

  • Low loss MOSFET, creating circuits with improved efficiency
  • High frequency operation which enables the downsizing of the coil

Line-up of 30V, 40V, 60V, 75V, and 100V breakdown voltages

  • Supports circuits with various input/output voltages

Line-up of DFN5×6, and TO252 packages

  • Space saving design to support various needs, from thin types to high power type applications

Entire series are 4.5V drive low Qg products

  • Supports various applications, including DC/DC converters, AC/DC power supply (secondary-side rectification), etc

※FOM(Figure of Merit)=Rds(on)×Qgd
