Capable of 4V drive operation
Ultrahigh-speed switching performance
Guaranteed avalanche resistance

Applications

Motor drive systems
DC / DC converters

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and compliance status. Confirm availability and lifecycle status directly with authorized distributors or the manufacturer, as component supply can change without notice. Ensure all technical parameters match the design requirements before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring robust N-channel switching with high current capacity. Consider the 4V drive compatibility for logic-level interfacing. Evaluate thermal management needs based on the specified power dissipation limits at ambient and case temperatures. Verify that the 100V rating aligns with the system's maximum operating voltage.

Part Context

This part belongs to the 2SK3821 series of N-channel silicon MOSFETs manufactured by onsemi (formerly SCILLC). It is housed in the SMP package, which corresponds to the TO-262VAR form factor. The device is engineered for general-purpose switching tasks, balancing low conduction losses with fast switching speeds suitable for power conversion circuits.

Replacement Considerations

Consult official substitution guides for verified equivalents. Cross-reference pinouts, voltage ratings, and package dimensions when considering alternative components.
