MMBF5484

Overview

The onsemi MMBF5484 is an N-channel RF amplifier JFET designed primarily for electronic switching applications, such as low on-resistance analog switching. It is sourced from Process 50 technology and housed in a SOT-23 package where the source and drain terminals are interchangeable. The device operates within a junction temperature range of -55°C to +150°C. Key electrical specifications include a maximum Drain-Gate Voltage of 25 V and a Gate-Source Voltage of -25 V. At TJ = 25°C, the Zero-Gate Voltage Drain Current (IDSS) ranges from 1.0 mA to 5.0 mA under VDS = 15 V conditions. The Gate-Source Cutoff Voltage (VGS(off)) spans from -0.3 V to -3.0 V at VDS = 15 V and ID = 10 nA.

Feature Summary

Designed specifically for electronic switching applications including low on-resistance analog switching
Features interchangeable source and drain terminals within the SOT-23 package
Sourced from Process 50 technology for consistent performance

Applications

Electronic switching circuits
Low on-resistance analog switching

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm that the received part matches the specific marking code '6xM' corresponding to the MMBF5484 variant. Ensure storage and handling procedures adhere to standard electrostatic discharge precautions for semiconductor devices.

Selection Notes

Select this component when designing circuits requiring N-channel JFETs for analog switching with low on-resistance characteristics. Consider the interchangeable pinout for flexible PCB layout. Evaluate thermal management requirements based on the specified junction-to-ambient thermal resistance for the target operating environment.

Part Context

The MMBF5484 belongs to a family of N-channel RF amplifiers manufactured by onsemi using Process 50 technology. It shares the same package and general design philosophy with the MMBF5485 and MMBF5486 models, differentiated primarily by their specific current and cutoff voltage parameters.
