TF256TH-3-TL-H

Overview

The TF256TH-3-TL-H is an N-channel Junction Field-Effect Transistor (JFET) manufactured by onsemi. It features a maximum drain current of 1 mA and is housed in a 3-VTFP surface-mount package. Key electrical parameters include a drain-source cutoff voltage of 100 mV at 1 µA, a maximum input capacitance of 3.1 pF at 2 V, and a typical zero-gate-voltage drain current of 140 µA at 2 V. The device supports a junction temperature up to 150°C and has a maximum power dissipation of 100 mW.

Feature Summary

N-channel JFET configuration for signal switching applications
Surface-mount 3-VTFP package design
Low input capacitance characteristics

Applications

Analog signal switching circuits
High-impedance buffer stages
Low-noise preamplifier inputs

Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer. Sourcing requires verification through authorized distributors or secondary market suppliers such as Rochester Electronics. Buyers must confirm authenticity and check for potential product change notifications before procurement.

Selection Notes

Engineers should evaluate the low drain current and specific cutoff voltage requirements against circuit needs. Due to the discontinued status, alternative components with compatible pinouts and electrical specifications within the same JFET family should be considered for new designs.

Part Context

The TF256 series belongs to onsemi's standard discrete semiconductor lineup, focusing on small-signal JFETs. These devices are part of the broader portfolio designed for precision analog applications, offering reliable performance in compact surface-mount formats suitable for modern electronic assemblies.
