BG5412KE6327HTSA1

Overview

The BG5412KE6327HTSA1 is a dual N-channel MOSFET tetrode designed for the input stages of two-band tuners. It integrates two AGC amplifiers within a single SOT-363 package, featuring an on-chip internal switch controlled by a single line. The device includes integrated gate protection diodes and ESD protection. Key electrical parameters include a drain-source voltage (VDS) of 8 V, continuous drain current (ID) of 25 mA per amplifier, and total power dissipation (Ptot) of 200 mW at case temperatures up to 94 °C. At 800 MHz, it achieves a typical noise figure of 1.1 dB for amplifier A and 1.2 dB for amplifier B.

Feature Summary

• Dual amplifier architecture with integrated switching capability
• Ultra-low noise figure optimized for tuner input stages
• Integrated ESD and gate protection diodes

Applications

• Input stages of two-band tuners
• Automatic Gain Control (AGC) amplifier circuits
• RF signal processing in communication equipment

Procurement Notes

Verify component authenticity through official Infineon channels or authorized distributors. Confirm that the ordering suffix matches the specific tape-and-reel packaging requirements for automated assembly. Ensure compliance with RoHS directives and AEC-Q101 qualification standards before integration into production designs.

Selection Notes

Select this component when designing compact tuner front-ends requiring dual low-noise amplification with gain control. Consider the 8 V maximum drain-source voltage and 25 mA current limits during biasing. Evaluate thermal resistance characteristics if operating near maximum power dissipation limits in high-density PCB layouts.

Part Context

This part belongs to the BG5412K series of dual MOSFET tetrodes from Infineon Technologies. It is specifically engineered for RF applications where space constraints and signal integrity are critical. The SOT-363 package allows for surface-mount integration in portable electronic devices requiring efficient use of board real estate.

Replacement Considerations

No official substitutes are listed in the datasheet. When evaluating alternatives, verify compatibility regarding pin configuration, maximum voltage ratings, and noise figure specifications. Ensure any replacement maintains the dual-amplifier topology and AGC control interface required by the original circuit design.
