Procurement Notes
Verify the exact part number suffix against the official ON Semiconductor website, as Fairchild Semiconductor integration may have updated naming conventions involving underscores versus dashes. Confirm availability status directly with authorized distributors, as this component may be classified as obsolete or not in production depending on the specific manufacturing lot and current inventory levels.
Selection Notes
Select the MMBF5460 when a P-Channel JFET with specific gate-source cut-off voltage ranges is required for audio or general-purpose amplification. Ensure the application supports the specified absolute maximum ratings for Drain-Gate and Gate-Source voltages. Consider the thermal resistance and power dissipation limits if operating in environments exceeding standard ambient temperatures.
