TF256-5-TL-H

Overview

The TF256-5-TL-H is an N-channel Junction Field-Effect Transistor (JFET) manufactured by onsemi. It is designed for surface-mount applications in a 3-VTFP package. The device supports a maximum continuous drain current of 1 mA and handles up to 100 mW of power dissipation. Key electrical characteristics include a gate-source cutoff voltage of 100 mV at 1 µA drain current and a maximum input capacitance of 3.1 pF measured at 2 V drain-source voltage. The component operates within a junction temperature range up to 150°C.

Feature Summary

• N-channel JFET configuration optimized for low-power signal processing
• Surface-mount construction in a compact 3-VTFP package
• High thermal stability supporting operation up to 150°C junction temperature

Applications

• Electret condenser microphone pre-amplification circuits
• Low-noise analog signal conditioning stages
• High-impedance sensor interface buffers

Procurement Notes

Verify the exact suffix '5' against official manufacturer documentation, as standard listings often reference the '4' variant. Confirm RoHS compliance status via the specific datasheet. Check for active obsolescence notices or production discontinuation announcements from onsemi before finalizing procurement plans.

Selection Notes

Select this component when a small-form-factor N-channel JFET with low input capacitance is required. Ensure the design accommodates the 3-VTFP footprint. Verify that the 1 mA drain current limit meets the circuit requirements. Compare specifications against similar devices like the TF202 series if alternative sourcing is necessary.

Part Context

This part belongs to the TF2xxTHC family of single N-channel JFETs. These components are typically utilized in audio and sensor applications requiring high input impedance. The TF256 designation indicates specific electrical parameters distinct from other members of the TF202 series, such as variations in cutoff voltage and capacitance.

Replacement Considerations

Publicly confirmed substitute part numbers for TF256-5-TL-H were not found in the provided source material. Consult onsemi technical support for verified cross-reference data.
