Procurement Notes

Verify the specific ordering suffix RH6327XTSA1 against official Infineon documentation to confirm tape-and-reel packaging specifications and marking details. Ensure compliance with RoHS requirements and AEC Q101 qualification status as stated in the datasheet before finalizing procurement orders.

Selection Notes

Select this component for designs requiring integrated dual-stage amplification within a compact SOT363 package. Consider the distinct drain current limits of 25 mA for amplifier A and 20 mA for amplifier B when designing biasing networks. Evaluate the thermal resistance characteristics if operating near maximum power dissipation limits.

Part Context

This part belongs to the BG3123 series of dual N-Channel MOSFET tetrodies designed specifically for tuner applications. The device consolidates two independent gain-controlled stages into a single surface-mount package, simplifying circuit board layout for broadcast receiver systems while maintaining signal integrity across UHF and VHF bands.

Replacement Considerations

No official substitute part numbers are documented in the provided source material. When evaluating alternatives, verify that replacement components match the SOT363 package dimensions, pin configuration, and electrical ratings such as the 8 V drain-source voltage limit.
