Overview
The onsemi 2N5486G is a silicon N-channel Junction Field-Effect Transistor (JFET) designed for RF small-signal applications in the Ultra High Frequency band. Housed in a TO-92 (TO-226AA) package, it operates in depletion mode with a maximum drain current of 30 mA and a feedback capacitance of 1 pF. The device supports a maximum operating temperature of 150 °C and features a Drain-Gate Voltage rating of 35 Vdc and a Reverse Gate-Source Voltage of 25 Vdc.
Feature Summary
- Optimized for low-noise amplification in VHF/UHF circuits
- High input impedance suitable for sensitive signal processing
- Robust thermal performance up to 150 °C junction temperature
Applications
- VHF/UHF amplifier stages
- Low-noise front-end modules
- RF signal conditioning circuits
Procurement Notes
Verify the specific suffix 'G' against the manufacturer's official documentation to confirm RoHS compliance status and exact pinout configuration. Ensure the procurement source provides valid traceability data for the TO-92 package variant. Cross-reference the part number with the latest datasheet revision to avoid discrepancies in absolute maximum ratings or electrical characteristics.
Selection Notes
Select this component when designing circuits requiring an N-channel JFET with high-frequency capabilities and low feedback capacitance. Consider the 30 mA drain current limit and 35 V Drain-Gate voltage rating during circuit analysis. Verify that the TO-92 through-hole package aligns with the target PCB layout constraints and thermal management requirements.
Part Context
The 2N5486G belongs to the 2N548x series of N-channel JFETs from onsemi. This family includes variants such as the 2N5484 and 2N5485, which share similar structural characteristics but differ in specific electrical parameters like cutoff voltage and zero-gate voltage drain current. The 2N5486G is specifically characterized for UHF band operations.
Replacement Considerations
Direct substitutes within the same series include the 2N5484 and 2N5485. Verify compatibility by comparing the gate-source cutoff voltage ranges and zero-gate voltage drain currents, as these parameters vary between the subtypes. Ensure the replacement maintains the required RF performance and package type.
