STD20NF06 MOSFET- Overview

The STD20NF06 is an N-Channel 60V VDSS, 24A ID, with less than 0.040 Ohms RDS(on) resistance MOSFET useful for high power and switching applications. The MOSFET works in ± 20V VGS. The below graph is useful to distinguish the drain current vs gate voltage specification-


The low RDS(on) provides very low power dissipation over the high current application and thus eliminates the additional use of a heatsink in a high current application where the PCB copper area can be utilized as the standard heatsink for the MOSFET.


How to Choose a MOSFET

  1. Choose the MOSFET type that is required for the application. STD20NF06LT is an N-Channel MOSFET.
  2. Calculate the maximum Drain to Source voltage that is required for the application. STD20NF06LT supports 60V Drain to Source supply voltage (VDSS).
  3. Calculate maximum Drain Current. Choose a MOSFET that could tolerate more than the Drain current that is actually required for the application. STD20NF06LT works up to 24A of Drain current (ID).
  4. Choose low RDS(on) resistance for the high current application for lower heat dissipations.
