2SC3837KT146N

Overview

The 2SC3837KT146N is a high-frequency NPN silicon small-signal transistor manufactured by ROHM Semiconductor. It operates in the Ultra High Frequency band with a maximum collector-emitter voltage of 20V and a maximum collector current of 50mA. The device features a typical transition frequency (fT) of 1500MHz, ensuring effective amplification at high frequencies. Key electrical characteristics include a DC current gain (hFE) range of 82 to 180, an output capacitance (Cob) of 0.9pF, and a collector-base time constant (rbb'·Cc) of 6ps. The component is housed in an SMT3 package and has a maximum power dissipation of 0.15W.

Feature Summary

High transition frequency for UHF band applications
Small rbb'·Cc and high gain characteristics
Low noise figure performance

Applications

High-frequency amplifier circuits
UHF band signal processing
General-purpose RF amplification

Procurement Notes

Verify the specific ordering suffix KT146N against official ROHM documentation to confirm packaging details and hFE grading. Confirm RoHS compliance status directly from the manufacturer's datasheet before procurement. Ensure the sourcing channel provides authentic components matching the specified SMT3 package dimensions and marking codes.

Selection Notes

Select this component when designing circuits requiring high-frequency operation up to 1.5GHz with low noise characteristics. Consider the 20V collector-emitter voltage limit and 0.15W power dissipation rating during thermal management planning. Evaluate the SMT3 package size constraints for surface-mount assembly processes.

Part Context

This part belongs to ROHM's high-frequency transistor lineup, sharing specifications with models like the 2SC5661, 2SC4725, and 2SC4082. These devices are designed for general-use electronic equipment such as audio-visual and communication devices. They are not intended for radiation-tolerant or safety-critical applications.

Replacement Considerations

The BD5237G-1 is listed as a replacement for the BU4837G, not the 2SC3837K. No direct public substitute part numbers are confirmed for the 2SC3837KT146N in the provided source material.
