BF245C_D75Z

Overview

The BF245C_D75Z is an N-channel depletion-mode JFET manufactured by onsemi. It is housed in a TO-92-3 (TO-226AA) package with formed leads for through-hole mounting. The device features a drain-source voltage rating of 30 V and a continuous drain current of 15 mA. It is classified as an RF small-signal transistor designed for high-frequency applications.

Feature Summary

• N-channel junction field-effect transistor technology
• Depletion mode operation for RF signal processing
• Through-hole compatible TO-92-3 leaded package

Applications

• UHF band amplification circuits
• VHF frequency oscillator stages
• RF mixer input stages

Procurement Notes

This component is officially marked as obsolete by the manufacturer. Verification of availability requires checking secondary market distributors or surplus suppliers. Ensure that any sourced units match the original datasheet specifications, as obsolescence may affect long-term supply chain stability and replacement sourcing strategies.

Selection Notes

Select this part for legacy designs requiring an N-channel JFET in a TO-92 package. Verify that the circuit requirements align with the 30 V breakdown limit and 15 mA current capacity. Consider pinout compatibility if replacing existing BF245 series components in established hardware architectures.

Part Context

The BF245C_D75Z belongs to the BF245 family of RF JFETs. The 'D75Z' suffix indicates specific packaging and tape-and-box handling configurations. This model represents a variant within the broader UHF/VHF amplifier transistor lineup produced by onsemi and its predecessor entities.

Replacement Considerations

Direct substitutes include BF245A and BF245B variants from the same family. Cross-reference electrical parameters such as transconductance and capacitance to ensure functional equivalence in RF applications.
