The 2SK3899-ZK-E1-AZ is an N-channel power MOSFET in a TO-263 package. It features a maximum drain-source voltage of 60 V and a continuous drain current of 84 A at 25°C case temperature. The device exhibits super low on-state resistance, with RDS(on) values of 5.3 mΩ max at VGS = 10 V and 6.5 mΩ max at VGS = 4.5 V, both tested at ID = 42 A. Input capacitance is typically 5500 pF. It includes a built-in gate protection diode for ESD safety.
Verify the specific suffix -E1-AZ against official Renesas documentation to confirm exact ordering specifications. Confirm quality grade classification before use. Ensure compliance with export control laws if applicable. Check latest datasheet versions for any parameter updates prior to design finalization.
Select based on required current handling and thermal dissipation needs. Consider the low RDS(on) characteristics for minimizing conduction losses. Evaluate the 60 V rating against system voltage peaks. Ensure adequate heat sinking for the specified power dissipation ratings.
This component belongs to the Renesas (formerly NEC Electronics) discrete semiconductor portfolio. It is designed as a robust switching element for power electronics. The TO-263 package facilitates surface mounting with direct thermal coupling to the PCB or heatsink.
Consult official Renesas documentation for verified substitute part numbers. Do not assume pin-compatible alternatives without verifying electrical parameters and package dimensions.
