2SK3800

Overview

The Sanken Electric USA Inc. 2SK3800 is an N-channel silicon MOSFET housed in a TO-220S package. It features a drain-source voltage rating of 40V and a continuous drain current capacity of 80A at a case temperature of 25°C. The device exhibits a maximum on-resistance of 5.0mΩ when driven by a gate-source voltage of 10V with a drain current of 35A. Thermal management relies on a junction-to-case thermal resistance of 1.56°C/W, supporting a maximum channel temperature of 150°C.

Feature Summary

N-channel enhancement mode metal-oxide semiconductor field-effect transistor
High continuous drain current capability up to 80 amperes
Low on-state resistance for efficient power switching
Guaranteed avalanche energy handling capability

Applications

Motor drive systems
DC/DC converter circuits
General-purpose switching applications

Procurement Notes

Verify the specific datasheet version and revision history before finalizing designs. Confirm that the TO-220S package dimensions match your PCB footprint requirements. Ensure thermal interface materials are selected to maintain the specified junction-to-case thermal resistance under actual operating conditions. Check for any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

This component is explicitly marked as not recommended for new designs. Engineers should evaluate alternative components from the manufacturer's current portfolio for future projects. Existing designs utilizing this part must ensure adequate thermal management due to the high current ratings. Verify that the 40V voltage rating provides sufficient margin for the target application's peak transient voltages.

Part Context
