2N5485_D74Z

Overview

The onsemi 2N5485_D74Z is an N-channel Junction Field-Effect Transistor (JFET) designed for RF applications. It operates within a voltage range of up to 25 V and supports a continuous drain current of 10 mA. The device features a power dissipation rating of 350 mW and functions across a temperature range from -55°C to +150°C. Packaged in a TO-92-3 through-hole configuration, it offers a forward transconductance between 0.0035 S and 0.007 S. This component is suitable for high-frequency circuits requiring stable amplification characteristics.

Feature Summary

• Optimized for radio frequency signal processing and amplification tasks
• Capable of operation at frequencies up to 400 MHz
• Constructed using silicon technology for reliable performance

Applications

• RF amplifier stages in communication equipment
• High-frequency signal processing circuits

Procurement Notes

Verify the obsolete status of this component before integration into new designs. Confirm RoHS compliance details with the manufacturer or authorized distributors. Ensure that the specific D74Z suffix matches the required packaging format for your assembly process. Cross-reference datasheet revisions to confirm parameter stability.

Selection Notes

Select this part when an N-channel JFET with a 25 V breakdown voltage and 10 mA current capacity is required. Consider the TO-92-3 package constraints for PCB layout. Evaluate the transconductance range against circuit gain requirements. Verify thermal management capabilities given the 350 mW dissipation limit in enclosed environments.

Part Context

This component belongs to the standard JFET family produced by onsemi. It shares core electrical specifications with variants like the 2N5485G but may differ in packaging or testing criteria. The D74Z designation specifically indicates the Ammo Pack shipping format used by certain distributors.
