MMBF5486

Overview

The onsemi MMBF5486 is a discontinued N-Channel RF Amplifier designed primarily for electronic switching applications, such as low On Resistance analog switching. Sourced from Process 50 technology, it operates within a Drain-Gate Voltage of 25 V and a Gate-Source Voltage of −25 V. The device features a Zero-Gate Voltage Drain Current (IDSS) ranging from 8.0 to 20 mA at VDS = 15 V. It exhibits a Gate-Source Cutoff Voltage (VGS(off)) between −2.0 V and −6.0 V under specified test conditions. Small signal characteristics include an Input Capacitance of 5.0 pF and a Reverse Transfer Capacitance of 1.0 pF at 1.0 MHz.

Feature Summary

• Designed for electronic switching applications including low On Resistance analog switching
• Features interchangeable source and drain terminals in the SOT-23 package
• Operates reliably across a wide temperature range from -55°C to +150°C

Applications

• Electronic switching circuits
• Low On Resistance analog switching

Procurement Notes

Verify component status before design finalization, as the MMBF5486 is officially marked as discontinued by onsemi. Confirm availability through authorized representatives or secondary markets if immediate procurement is required. Ensure that any replacement components meet the original electrical specifications and thermal requirements to maintain system integrity.

Selection Notes

Select this component based on its specific N-Channel JFET characteristics and Process 50 sourcing. Consider the interchangeability of source and drain pins during PCB layout to simplify routing. Evaluate the cutoff voltage range (-2.0 V to -6.0 V) against control logic levels to ensure proper switching thresholds are met in the target application environment.

Part Context

The MMBF5486 belongs to a family of N-Channel RF amplifiers manufactured by onsemi using Process 50 technology. It shares similarities with the MMBF5484 and MMBF5485 models, differing primarily in threshold voltage and current parameters. These devices are housed in the SOT-23 (TO-236) surface-mount package, providing a compact solution for RF and switching applications requiring small form factors.
