2SK3801

Overview

The Sanken Electric USA Inc. 2SK3801 is a silicon N-channel power MOSFET housed in a TO-3PA package. It features a drain-source breakdown voltage of 40V and a continuous drain current rating of 100A at a case temperature of 25°C. The device exhibits a maximum on-resistance of 5.0mΩ at VGS=10V and ID=35A. Key electrical parameters include a gate-source leakage current of ±10µA, a threshold voltage range of 2.0V to 4.0V, and an input capacitance of 1200pF. Thermal characteristics specify a junction-to-case thermal resistance of 1.25°C/W and a junction-to-ambient resistance of 35.71°C/W.

Feature Summary

High current handling capability with a 100A continuous drain current rating
Low on-state resistance for efficient power conduction
Robust thermal management with low junction-to-case thermal resistance
Defined safe operating area for single pulse applications

Applications

Power conversion circuits requiring high current switching
Automotive auxiliary systems utilizing 40V architectures
Industrial equipment power stages
Motor driver output stages

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pinout and packaging configuration. Confirm that the component meets the required automotive functional safety standards if intended for ASIL D applications. Check for RoHS compliance status and verify the manufacturing date code to ensure stock freshness. Ensure the supplier provides valid traceability documentation for critical industrial or automotive deployments.

Selection Notes

Select this component when a 40V N-channel MOSFET with high current capacity is required. The TO-3PA package facilitates direct mounting to heatsinks, simplifying thermal design for high-power applications. Consider the 5.0mΩ maximum RDS(on) for efficiency calculations at 35A loads. Evaluate the 100A pulsed current rating against peak load requirements within the specified duty cycle limits.
