2SC4083T106P

Overview

The 2SC4083T106P is an NPN silicon high-frequency amplifier transistor manufactured by Rohm Semiconductor. It operates with a collector-emitter voltage of 11V and a maximum collector current of 50mA, dissipating up to 200mW. The device features a transition frequency (fT) of 3.2GHz at 500MHz, output capacitance of 0.8pF, and a noise figure of 3.5dB. Encased in a UMT3 (SOT-323/SC-70) surface-mount package, it supports junction temperatures up to 150°C.

Feature Summary

• High transition frequency for ultra-high frequency applications
• Low base resistance and small output capacitance for high gain
• Optimized low noise figure characteristics

Applications

• UHF/VHF frequency converter circuits
• Local oscillator stages

Procurement Notes

Verify the specific suffix 'P' against official Rohm documentation to confirm its exact meaning regarding binning or marking, as datasheets primarily reference the T106 taping code. Ensure ESD protection measures are implemented during handling due to electrostatic sensitivity warnings in the product notice.

Selection Notes

Select this component for designs requiring high-speed switching or amplification in the UHF band. Consider the 11V breakdown limit and 50mA current rating when sizing external biasing networks. Verify that the UMT3 package dimensions align with the target PCB footprint constraints.

Part Context

This part belongs to the 2SC4083 series of high-frequency transistors from Rohm. It is designed specifically for RF signal processing tasks where low noise and high speed are critical. The device complements other components in UHF receiver and transmitter architectures.
