J310_D75Z

Overview

The onsemi J310_D75Z is an N-channel Junction Field-Effect Transistor (JFET) designed for VHF and UHF amplifier applications. It operates within a frequency range up to 450MHz, providing a typical gain of 12dB. The device features a maximum drain-source voltage of 10V and a drain current rating of 10mA. Packaged in a TO-92-3 configuration, it supports surface or through-hole mounting depending on the specific variant requirements.

Feature Summary

• Optimized for VHF and UHF signal amplification
• High gain performance at radio frequencies
• Compact three-terminal package design

Applications

• VHF amplifier circuits
• UHF amplifier stages
• RF signal processing modules

Procurement Notes

Verify the exact suffix designation against official manufacturer documentation to confirm pinout and electrical tolerances. Ensure the selected variant matches the required thermal and voltage specifications for the target RF application environment before finalizing procurement orders.

Selection Notes

Select this component for designs requiring discrete N-channel JFETs in the VHF/UHF spectrum. Evaluate the 10V breakdown limit and 10mA current capacity against circuit load requirements. Confirm compatibility with the TO-92-3 footprint during PCB layout planning.

Part Context

This part belongs to the J310 series of RF JFETs manufactured by onsemi. It serves as a specialized active component for high-frequency analog signal chains, distinct from standard low-frequency switching transistors due to its optimized noise figure and gain characteristics at radio frequencies.
