BF256A

Overview

The BF256A is an N-channel Junction Field-Effect Transistor (JFET) designed for VHF and UHF amplifier applications. It operates in depletion mode and utilizes a single FET configuration within a TO-92 package. The device is lead-free and RoHS compliant, featuring a cylindrical plastic body with three terminals. It supports operation up to a maximum junction temperature of 150 °C and is classified under the Ultra High Frequency Band.

Feature Summary

Engineered specifically for VHF and UHF amplifier circuits
Utilizes N-channel JFET technology for signal amplification
Operates in depletion mode with a single FET configuration

Applications

VHF amplifier stages
UHF amplifier stages
General-purpose RF signal processing

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm the package type matches the required TO-92 form factor. Ensure the device meets environmental compliance standards such as RoHS if applicable to the target assembly. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when designing circuits requiring N-channel JFETs for high-frequency amplification tasks. Consider the TO-92 package constraints regarding thermal management and board space. Evaluate the depletion mode operation characteristics against circuit biasing requirements. Compare performance metrics with alternative JFETs like the 2N3819 or BF245A if specific parameter adjustments are needed.

Part Context

The BF256A belongs to a family of N-channel JFETs produced by ON Semiconductor and other manufacturers such as Fairchild and National Semiconductor. These devices are commonly used in radio frequency applications due to their low noise and high input impedance characteristics. The TO-92 package provides a compact solution for discrete transistor implementations in consumer and industrial electronics.

Replacement Considerations

Potential substitutes include the BF256, BF245A, and 2N3819. Verify pinout compatibility and electrical parameters such as Idss and Vgs(off) before substitution. Ensure the replacement device meets the same frequency and power requirements.
