Overview
The BF199_D74Z is a small-signal N-channel Junction Field-Effect Transistor (JFET) manufactured by onsemi. It is housed in a TO-92 through-hole package, designated by the suffix D74Z. The device operates in depletion mode and is constructed using silicon technology. Key electrical characteristics include a maximum drain-source breakdown voltage of 30V and a gate-source cutoff voltage ranging from -0.5V to -6V. The component supports a continuous drain current of up to 10mA and features a low input capacitance typical for RF applications.
Feature Summary
- Designed for high-frequency amplification and switching applications
- Low noise performance suitable for sensitive signal processing
- Interchangeable source and drain terminals for flexible circuit layout
Applications
- RF amplifier stages
- High-frequency oscillators
- Low-noise preamplifiers
Procurement Notes
Verify the specific datasheet version for the BF199 series from onsemi to confirm exact electrical limits and thermal resistance values. Ensure the TO-92 package variant matches the required pinout configuration for the target PCB design. Cross-reference with legacy Fairchild Semiconductor documentation if sourcing from older inventory batches.
Selection Notes
Select this component for circuits requiring low-noise N-channel JFETs in the VHF/UHF range. Consider the 30V breakdown limit when designing power supply rails. The TO-92 package is suitable for prototyping and low-volume production where surface-mount space is not a constraint.
Part Context
This part belongs to the BF199 family of small-signal JFETs, historically significant in radio frequency engineering. The D74Z suffix indicates the specific plastic encapsulation and lead form factor provided by onsemi. It serves as a direct replacement for earlier iterations produced by Fairchild Semiconductor before the acquisition.
Replacement Considerations
BF199 variants from other manufacturers may be compatible if pinouts match. Verify gate-source voltage thresholds against original design requirements.
