2SK3746

Overview

The 2SK3746 is a small signal N-channel silicon MOSFET designed for low-noise applications. It features a maximum drain-to-source voltage of 15V and a continuous drain current of 0.03A. The device utilizes an MCP package with three terminals. Key electrical characteristics include a gate-to-source voltage limit of ±15V and a maximum allowable power dissipation of 0.15W. The component operates within a channel temperature range up to 150°C and supports storage temperatures consistent with standard semiconductor specifications.

Feature Summary

N-channel silicon construction for reliable small-signal switching
Low noise performance suitable for sensitive circuit stages
High power gain capability in amplifier configurations
Small reverse transfer capacitance for improved stability

Applications

FM tuner input stages
VHF amplifier circuits
Low-noise signal processing

Procurement Notes

Verify the manufacturer designation carefully, as the model number 2SK3746 is primarily associated with onsemi as a high-voltage power MOSFET. Confirm that the specific low-voltage Sanyo variant matches the required 15V rating and 0.03A current limits before integration. Ensure the MCP package type aligns with the PCB footprint requirements.

Selection Notes

Select this component for applications requiring low noise and high power gain at low voltages. The small reverse transfer capacitance makes it suitable for VHF frequencies. Verify that the 15V breakdown voltage is sufficient for the specific circuit operating conditions and that the 0.03A current rating meets the load requirements.

Part Context

This part belongs to the category of small signal field-effect transistors manufactured by Sanyo. It is distinct from higher-power variants sharing similar numbering conventions. The device is engineered for specific RF and audio frequency applications where low noise figure is critical.
