BF256C_J35Z

Overview

The onsemi BF256C_J35Z is a discontinued N-channel Junction Field-Effect Transistor (JFET) designed for radio frequency applications. It utilizes the TO-92-3 through-hole package, also designated as TO-226AA. The device operates with a rated voltage of 30V and supports a maximum drain current of 18mA. This component belongs to the BF256 series, which includes variants such as the BF256A and BF256B. As an obsolete part, it is no longer in active manufacturing.

Feature Summary

• N-channel JFET configuration optimized for RF signal processing
• Through-hole TO-92-3 standard body packaging for reliable mounting

Applications

• Radio frequency amplification circuits
• Ultra high frequency band signal processing
• Low noise amplifier stages

Procurement Notes

This specific part number is officially marked as obsolete and no longer manufactured by onsemi. Verification of availability should focus on surplus distributors or secondary markets rather than direct manufacturer channels. Buyers must confirm the authenticity of existing stock due to the discontinuation status.

Selection Notes

Designers requiring this component should evaluate the MMBF5485 as a verified similar replacement offered by onsemi. Since the original part is discontinued, alternative sourcing strategies must account for potential supply chain limitations. Compatibility checks are necessary when substituting with other JFETs from the same family.

Part Context

The BF256C_J35Z is part of the broader BF256 series produced by onsemi. This series encompasses multiple variants differentiated by specific electrical characteristics within the same package type. The J35Z suffix likely denotes a specific binning or screening level, though detailed differentiation data is not publicly documented.

Replacement Considerations

The MMBF5485 is listed as a similar replacement part available from onsemi.
