BF245C_D27Z

Overview

The BF245C_D27Z is an N-channel depletion-mode Junction Field-Effect Transistor (JFET) manufactured by onsemi. Designed for VHF and UHF amplifier applications, this component operates within a drain-source voltage range of up to 30V and supports a continuous drain current of 100mA. The device utilizes a TO-92 surface-mount package configuration, ensuring compatibility with automated assembly processes while maintaining the electrical characteristics required for high-frequency signal amplification in consumer and industrial electronics.

Feature Summary

• Optimized for VHF and UHF frequency band amplification
• N-channel depletion mode operation for stable biasing
• Surface-mount compatible TO-92 packaging

Applications

• VHF/UHF RF amplifier stages
• Low-noise front-end circuits
• Impedance matching networks

Procurement Notes

Verify the specific suffix _D27Z against official onsemi documentation to confirm tape-and-reel packaging specifications and lot traceability requirements. Ensure that the ordering part number matches the exact pinout and thermal characteristics defined in the current datasheet revision before finalizing procurement contracts.

Selection Notes

Select this component when designing circuits requiring N-channel JFETs for VHF or UHF frequencies. Consider the 30V breakdown voltage and 100mA current limits during schematic design. Verify that the TO-92 SMD footprint aligns with the PCB layout constraints and that the thermal dissipation capabilities meet the system's power budget under maximum operating conditions.

Part Context

This part belongs to the BF245 family of N-channel silicon JFETs produced by onsemi. It shares functional similarities with other devices in the series, such as the BF245A and BF245B, which are also designed for VHF/UHF amplification. The D27Z suffix typically indicates a specific packaging or reel variant rather than a change in core electrical performance parameters.

Replacement Considerations

Direct substitutes include the BF245A and BF245B from onsemi, provided the pinout remains identical. Other manufacturers may offer equivalent N-channel depletion JFETs, but verification of the specific gain group and capacitance values is required to ensure circuit stability.
