J202 TO-92 3L ROHS

Overview

The J202 is a single N-channel Junction Field-Effect Transistor (JFET) amplifier manufactured by Linear Integrated Systems, Inc. in a TO-92 three-lead plastic package. It operates with a maximum continuous power dissipation of 350mW at +25°C and supports junction temperatures up to +150°C. The device features a gate-to-source breakdown voltage of -40V and a gate-to-drain breakdown voltage of -40V. Electrical characteristics include a drain-to-source saturation current ranging from 0.9mA to 4.5mA at VDS=15V and VGS=0V, and a forward transconductance of 1.0mS under the same conditions. Input capacitance is typically 4.5pF, and noise voltage is specified at 4.0nV/√Hz.

Feature Summary

High input impedance suitable for high sensitivity applications
Very low noise performance for precision signal processing
Low cutoff voltage enabling operation with minimal supply voltages
High gain capability for low-level signal amplification

Applications

High-gain, low-noise amplifiers
Low-current, low-voltage battery-powered amplifiers
Infrared detector amplifiers
Ultra-high input impedance pre-amplifiers

Procurement Notes

Verify that the ordered component matches the exact part number J202 TO-92 3L RoHS as listed in the official ordering information. Confirm compliance with RoHS standards if required by your manufacturing process. Ensure the package type corresponds to the standard through-hole TO-92 configuration. Cross-reference the manufacturer's datasheet specifications against your circuit requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring high input impedance and low noise characteristics. Consider the specific VGS(off) range of -0.8V to -4.0V for biasing stability. Evaluate the forward transconductance of 1.0mS for gain requirements. Ensure the operating environment stays within the specified temperature limits of -55°C to +150°C for reliable performance.

Part Context

This component belongs to the J/SST201/2/4 series of single N-channel JFET amplifiers. It serves as a direct replacement for legacy Siliconix devices in similar form factors. The series includes variants like J201 and J204, differentiated primarily by their cutoff voltage ranges and saturation currents. All parts share common electrical characteristics such as low leakage and high gain capabilities.

Replacement Considerations

The J202 is documented as a direct replacement for the Siliconix J202. Verify pinout compatibility between the original Siliconix component and the Linear Integrated Systems version to ensure seamless integration without circuit modification.

FAQ

What is the typical forward transconductance of the J202?

The typical forward transconductance (gfs) is 1.0mS at VDS = 15V, VGS = 0.0V, and f = 1kHz.

What is the maximum gate-to-source voltage rating?

The maximum gate-to-source voltage (VGSS) is rated at 40V.

Does the J202 support surface-mount assembly?

No, the J202 specifically refers to the TO-92 through-hole package. Surface-mount versions are available under the SST202 designation in the SOT-23 package.
